# 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 support@cheenta.com. Though we usually look into internal students work, we will try to give you some feedback.
