 Problem 1 

This problem has three parts:

a) State the Fundamental Theorem of Calculus.

b) Compute   ${\frac {d}{dx}}\int _{0}^{\cos(x)}\sin(t)~dt$.

c) Evaluate $\int _{0}^{\pi /4}\sec ^{2}x~dx$.

 Problem 2 

Evaluate

a)   $\int _{1}^{2}{\bigg (}2t+{\frac {3}{t^{2}}}{\bigg )}{\bigg (}4t^{2}-{\frac {5}{t}}{\bigg )}~dt$

b)   $\int _{0}^{2}(x^{3}+x){\sqrt {x^{4}+2x^{2}+4}}~dx$
