 # 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.
