Answer 1

\(\large\color{black}{ \displaystyle y=s\sqrt{1-s^2}+\cos^{-1}s }\)

What problem do you have with differentiating the above?

Answer 2

Can you use the *Product Rule* for the following? \(\large\color{black}{ \displaystyle s\sqrt{1-s^2} }\)

Answer 3

I used the product rule and derived the arccos and got
