We had to change all our course images on Udemy due to (I think) new rules. All those math symbols weren’t acceptable, so we had to make the images *really* simple. Probably for the best, I have to admit.

*really* simple. Probably for the best, I have to admit.

Will you be making an in depth course in statistics? I notice that it’s not on your outline. Can you please make one? I’m going to take statistics in a year from now and I could use your guidance.

I’m not certain about that. If I get to make a statistics course, it will be in 2024 at the earliest, because I really want to implement my master plan first. Sorry to disappoint you.

/Hania

I understand. Can you try if possible to release it before the end of 2023?

Hi Allen,

By the end of 2023 would be extremely difficult… I would almost say impossible. I really want to be thorough and as complete as possible in my Precalculus and Calculus series, because they build the fundament for all the future studies of more advanced topics.

Sorry, again, for disappointing you…

Kind regards,

Hania

Dear Hania

You should not just for the quick release of the course but reduce the quality of the course, but you should plan for a course on statistical probabilities on the future, I really need to learn from you, just like many people also want to have one course on statistical probabilities,not only me, there are many requests for a statistics course from you.

Work is busy, but you need to pay attention to your health to have the best health for work

Thank you!

Dear My Cool,

You are absolutely right: it is important to care for health. For me, an important element contributing to my health and wellbeing is the conviction that I have done my best creating my courses, and that I have published courses of hight quality. So rushing with courses is not an option for me, indeed, as I am not ready to reduce the quality of my work or harm my health.

Moreover, I really LOVE teaching mathematics (which sure contributes to the quality of the courses) and I am not quite sure if I would love teaching statistics π Actually, I never did teach statistics, but I have an extensive experience in teaching mathematics. Then it is logical for me to start with the subjects which I really master, so that I can serve my students with a high-quality expertise.

I actually know a statistician, who is also an excellent teacher. Maybe I can convince her to create a Udemy course in statistics?

Kind regards,

Hania

YESSS try and convince her so many of us want a stats and probability course from basics to advanced π

Hey guys, any news about precalc 2?

Adam,

Any day now. Almost any hour. We actually finished all the recordings, just doing the last reviewing and patching of glitches found. So we’ll probably clear for publishing tomorrow, then it takes anything between a day or a few days for Udemy to enable it publicly.

Adam,

The new course, Precalculus 2, is up now. See the blog post and the “Coupon codes” link for codes.

Dear Professor Hania

I hope you add these math courses to your master plan

these are undergrads modules taught for engineers and mathematicians

I am not locked to a particular time frame so you could work on

them at the time that suits you

I’d like to know when to expect to see them

-probability

-statistics

-Laplace transform and its applications

-Fourier analysis

-partial differential equations (PDE) and special functions ( Gamma , Betta , Legendre and Bessel functions)

-numerical analysis

-Real analysis

Dear Ahmed,

Thank you for the list! The first one will be Real analysis: I usually include parts of Real analysis in my Calculus courses, which are more strict than typical Calculus courses. I have already made a preparation for this in “Precalculus 1: Basic notions” by including axioms of real numbers and discussing the epsilon-delta definition of limits.

As for the other courses on your list: I will definitely keep them in mind, but my personal list is already so full that I cannot promise anything else for the near future.

Kind regards,

Hania

okay , you stated in your roadmap that you plan to create a differential equations course

so let’s forget about the probability / statistics / numerical analysis

for a while and focus on the other four

Laplace / Fourier / PDE (but not in depth) / special functions (legendre and bessel)

these four are related and most of the times are included in the differential equations course so will you include them in your differential equations course

you could see them include in these two playlists taught by professors from two different universities

I am very interested to see your version of the differential equations

I am pretty sure it will be great

Hi Ahmed,

Thank you for the links! I like both courses, just the tablet they are using for writing stuff is awful π

Also thank you for believing in me, that my ODE course would be great. You know, though, that it is planned for 2024, so by now you have to rely on these two guys… Moreover, my planned ODE course will be quite basic: linear, systems of linear, separable,… It is possible that I will make a more advanced course later.

Kind regards,

Hania

well 2024 isn’t that far I can wait no problem I have a lot to do until that time and also according to the roadmap there are plenty of math courses will be released until that time

the point is when I mentioned these four topics in the comment above my guess was that you will deal with the ODE the same way you dealt with linear algebra you covered it from every aspect there ‘s no topic I could think of and I could not find in your course (it is the best online linear algebra course so far) and this had been done through three parts so I really hope you will do you the same with the ODE and cover it through 2 or three parts ( first part is the basic , 2nd is the intermediate , the third is advanced)

the last thing I really appreciate the great effort you put into the creation of these courses can’t wait to see more courses from you

Hi Ahmed,

I will do my best to cover ODE in a really thorough way. I don’t think that I am able teach in a different way; I simply wouldn’t create any course on a matter I don’t master in a sufficient way to make it understandable for everybody.

Thank you for your kind words about my courses; If you don’t mind, it would be really nice if you wrote a review on Udemy, telling the other (potential) students what you like in my courses. It would help a lot in attracting new students π

Kind regards,

Hania

“I will do my best to cover ODE in a really thorough way”

that is so great to hear that you will cover it in a comprehensive way thank you very much

————————————————-

“I simply wouldnβt create any course on a matter I donβt master in a sufficient way to make it understandable for everybody”.

-I am so glad to hear this , that you are putting a great effort in order to deliver a high end quality content , salute to you

“Thank you for your kind words about my courses; If you donβt mind, it would be really nice if you wrote a review on Udemy, telling the other (potential) students what you like in my courses. It would help a lot in attracting new students”

– I haven’t bought the course yet but I saw the preview videos and the reviewed entire syllabus and I am really very very amazed by what I saw and once I do buy it I’ll share my thoughts regarding it and write a review I have been looking for a linear algebra course for about three years and I have seen a lot of them (free-paid) and yours is so far the best of them I mean you cover it in about 150 hours it is just unbelievable and with high quality videos and explanations so you preserved both quality and quantity

Oh, no problem! Thank you for the comment, and for all the kind words about my courses π

Kind regards,

Hania

Hi Professor Hania

Since you plan to create calculus 2 content (integration and differentiation)

——

will you include the gamma and betta function in the integration part they are usually taught in this course as an application on the improper integration since both involve integration to infinity

———

Also will the differentiation part include the differentiation under the integral sign

Thanks in advance

Hi Ahmed,

Usually I don’t teach about gamma and beta functions in Calc2 courses, but I do teach improper integrals. But, because you ask this question, I will consider including these functions in my upcoming course Calc2 anyway.

Differentiation under the integral sign: not a topic of Calc2 either, rather Real Analysis.

It is possible, though, that I will make an extension “Calculus and Real Analysis: some more advanced topics”, and then I can include this kind of stuff there.

My observation is that advanced courses don’t sell too well on Udemy (our Calculus 3 / Multivariable Calculus sells much slower than Precalculus and Linear Algebra and Geometry), so, before I move towards the advanced topics, I would like to have enough of basic stuff to be able to finance the production of the more advanced stuff. The reason why I started with this advanced course (Calc3) was that I thought that this would be my only course on Udemy, and it happened to be my favourite. Then, the situation changed, and we decided to concentrate on Udemy for 100%, giving up our day jobs. Then we developed the Master Plan π

Kind regards,

Hania

Dear Dr Hania

Could you consider trying to complete precalculus courses 1-4 this year? 2023 will be the year for calculus 1 and 2, it’s already mid-August, a year is almost over and we don’t have much time left.

Donβt forget to have a good breakfast if you want to be healthy at work. Love you

Best Wishes!

Ming

Dear Ming,

Thank you for your kind message, and thank you for caring. I appreciate it.

Yes, it is still my ambition to complete the entire Precalculus series by the end of 2022. I will now make a very short free course (Mathematics: Fun tricks for everybody): I prepared it already in the beginning of July, but I am waiting with the recordings for the start of school (here in Sweden, this year: August the 18th), so that I get a silent house. After that (some days) I begin to work on Precalculus 3: Trigonometry.

Kind regards,

Hania

yeah

I think you should manage the division of work by time more reasonably, because 4 months to have 2 courses but still ensure quality is a job that requires great concentration.

I know — I am master of great concentration π

The plan is just a roadmap, nothing that binds us; if it doesn’t work out, then we adapt the plan to reality. Maybe the deadline will suffer, but the quality (of both our courses *and* our life) will not!

Hi Hania

Exercises to practice and consolidate knowledge are very important, in each course, hoping you will create more exercise solving videos, each exercise has different characteristics, besides the exercises that requires computation thinking, assignments related to proofs is very nescessary, every student has the mentality that they will learn to be fully equipped with knowledge in one study, instead of having to add another book , it would be great to just need study your course is enough.

Thanks again!

Hi Ming,

You are so right about the importance of exercise. But… all of my courses contain plenty of exercises. They are just not formulated as assignments or quizzes, but they are there (listed in long lists like for example http://wehlou.com/hania/files/uu/Outline_Precalculus1.pdf).

Also, all my courses are created in such a way that you actually don’t need any book. Sometimes I add a book anyway (like for my Precalculus courses), for those who want to practice even more than what already is offered in my courses, but you get enough of stuff (theory, proofs, exercises) in my course only.

Which course in particular are you referring to? Is the course you are referring to lacking something? (If so, please, tell me what. I can add more material in the future if needed, but now I find it really important to create new courses, so that my students get complete series. Enriching existing courses can wait, I think… especially because they already are much larger and more detailed than the most Udemy courses.)

Kind regards,

Hania

Hi Hania

Although the discrete math topic won’t be released until 2024, I’m looking forward to that day, I think the discrete math book by Ms. Susanna S. Epp well, you should buy the book as lecture material for the discrete math course in 2024.

Thank you so much!

I will keep it op my shopping list π — thank you!

Dear Hania

I see our master plan is missing courses: Real analysis, Complex analysis, Function analysis, Measure theory, Probability and Statistics theory, Distribution theory, I don’t know if these courses have anything to do with the courses learn “linear algebra and calculus , in other words are these courses a prerequisite or supplement for calculus and linear algebra , you are a professional please review and add these courses to master plans, if they are meaningful in building foundational or complementary knowledge. I am afraid that when I study one topic, I lack a background knowledge in another subject, the background knowledge I don’t even know its presence or name, I have experienced it in some courses, so I have felt this suffering.

Thanks so much!

Real analysis, Complex analysis, Function analysis, Measure theory, Probability and Statistics theory, Distribution theory, besides these names, there is also “Manifolds”, I forgot to list in the previous message.

Thanks again

Dear Ming,

Yes, you are right, there is plenty of topics which are not on our master plan. Our first priority is to cover the subjects which are on our list, because they form a basis for all more advanced studies in mathematics.

Later we can expand the plan, but right now our time is filled until 2025. Putting too many titles on the list (at once) would be overwhelming for me, so I would rather wait.

Kind regards,

Hania

PS. There are some elements needed for Real Analysis in my Precalculus 1 course, as I plan to include some elements of Real Analysis in my upcoming Calculus series. No complete course of Real Analysis (yet), though.
