Looks like homework, doesn't it?

Where are your attempts in MC15?

What have you already tried?

 

BTW, the condition f(x)>= sine is somewhat strange.
First task should be to make a plot (either by hand or via Mathcad) which shows that you are just looking for the minimum of the part of the curve plotted thick red. Fortunately this minimum (green dot) can be found easily using the zero of the first derivative ...

The name "arctg" is quite outdated and should no longer be used according to the current standard (ISO 80000-2)

In Mathcad this function is called "atan".
