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.

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.
