Understand the problem

In the range 0f \( 0 \leq x \leq 2 \pi \) , the equation \( \cos (\sin (x) ) = \frac{1}{2} \) has how many solutions?

Tutorial Problems… try these before watching the video.

1. Show geometrically that \( \cos ( \frac{\pi}{3} ) = \frac{1}{2} \).

2. How does the graph of cos (sin(x)) looks like? What if you drew f(x)) = cos(cos(cos(x)))?

You may send solutions to Though we usually look into internal students work, we will try to give you some feedback.
