Dear Hania

how are you?

I want to ask a question, is calculus a prerequisite to know before learning discrete math? I am very interested in discrete math.

besides the course on statistical probability, would it be better to have a plan on the Numerical Methods course?

Thanks so much!

Dear My Cool,

Thank you, I am fine, and I hope the same for you 🙂

You don’t need Calculus at all to study Discrete math, not that I can think of (maybe in some examples? But, if so, I am sure that you will not miss much by just skipping these examples!). The only prerequisite for Discrete math is basically just high-school math. Maybe you need some more advanced stuff for Discrete math 2, but not Calculus. Calculus is all about continuity, and “continuous” is kind of counterpart of “discrete”.

Numerical Methods: I will keep it in mind. This course would definitely be different than my “regular” courses, as you need a lot of programming for demonstrating the methods. More work for Martin then, as he is doing all the programming I need.

Kind regards,

Hania

Hi Hania

Because in discrete math there are mentioned some proof techniques, which they apply in calculus, so I don’t know which one to learn first.

yes i think python would be reasonable in numerical analysis course

thanks!

Oh, you don’t need Calculus for proof techniques: I have them covered in my Precalculus 1 course. Have a look at Section 11:

According to me, you don’t have to study Calculus before Discrete math. That you *afterwards* use the techniques for Calculus doesn’t mean that you must master Calculus while learning the techniques. Again, you will possible miss one or two examples…

Dear Hania

Should i learn calculus or linear algebra first?

I found out that people say that to learn multivariate calculus requires a bit of linear algebra, but I don’t know what linear algebraic knowledge needs to be used in multivariable analysis? Which one should I start learning first will be more beneficial later?

thanks!

Dear My Cool,

If you don’t know linear algebra at all, I would say: study it first. It is much more elementary than Calculus, you can even study it coming straight from high school.

If you studied linear algebra before, and you have studied Calculus 1+2, you can start Calculus 3 right away. I have included (in my Calc3 courses) some preliminaries, what you need to know from linear algebra, so I don’t really assume that the students know all the topics. But I assume that the students know both Calc 1 and 2 when they start Calc 3.

You can try linear algebra and you can try Calculus 3 and see which one you like the most. Keep studying this one then, and ask me questions (there is a nice Q&A on Udemy) if you need some more explanations than the one given in the lectures. I will be happy to help.

Kind regards,

Hania
