The course is challenging. I learned a lot about trigonometric functions and their behavior. I can now understand periodic ODEs better now...

Excellent course. Trigonometric concepts that, in previous courses, had been intimidating, confusing and tedious became dramatically less so.

From the lesson
Module 3: Sine and Cosine as Periodic Functions
Sine and cosine are now introduced using the unit circle, which is the circle centered at the origin with radius one. This definition of our key periodic functions extends the definition originally introduced with right triangles.
