Precalculus 3: trigonometry
A total of 52 hours of lectures
Due to the size of precalculus, it is divided into four parts. This page describes the third of those four parts.
Prerequisites
- High-school mathematics, mainly arithmetic; solving simple equations (linear and quadratic) with one unknown; some (but very few) polynomial equations will be solved during the course, but you can skip them if you want to (no problem at all; it will not affect your understanding of trigonometry).
- Precalculus 1: Basic notions (mainly the concept of function and related concepts; sets; logic)
-
You will get a very brief introduction to *complex numbers* in this course, just enough for presenting one of applications of trigonometry, and for a nice illustration of the formulas for sine and cosine of a sum
-
Some basic geometry (angles, triangles, polygons); a crash course (6 hours) is provided in Section 2 of this course (can be skipped if you feel that you master basics of geometry)
Curriculum
Make sure that you check with your professor what parts of the course you will need for your exam. Such things vary from country to country, from university to university, and they can even vary from year to year at the same university.

If you are struggling with math and your goal is to understand the topics deeply, then Hania’s courses will never disappoint you. The content is great and perfectly structured. The difference between Hania’s and other courses is that other courses focus too much on problem solving without understanding the problem first, whereas Hania will firstly teach you the core concepts and will give you all the tools you need to before diving into problem solving session. It is really great and rewarding content. 10/10
