Yes, apply the fundamental theorem of Calculus.

Answer 3

Okay how do I do that?

Answer 4

Just to clarify, is the function supposed to be f(t)=... ?

Answer 5

f(x) =

Answer 6

\[\int\limits_t^\left\{ -1 \right\} \ln (t^2+1)dt=F(-1)-F(t)\]
About the differentiation, I believe it will be sufficient to derive it with respect to t, or just view t as a function of x

t=x(t)
