if x=2 , f(x)=1

if x=3 , f(x)=4

if x=5 , f(x)=-2

if x=8 , f(x)=3

if x=13 , f(x)=6

f is twice variable for all real numbers.

1. Find f'(4)

2. Approximate${\underset{2}{\int}}^{13}{f}^{\prime}\left(x\right)dx$

2. Find the value of${\underset{2}{\int}}^{8}(3-{f}^{\prime}\left(x\right))dx$

I have a question thatasks me to find an algebraic expression for $\mathrm{sin}\left(\mathrm{arccos}\left(x\right)\right)$ . From the lone example in the book I seen they're doing some multistep thing with the identities, but I'm just not even sure where to start here. It's supposed to be $\sqrt{1-{x}^{2}}$
