Definite Integral - IS (A)
Consider the integral $\displaystyle I=\int_{0}^{a} 2\sqrt{a^2-x^2}dx$ and the change of variable $x=a \sin(t)$. So $I$ comes equal to:
# Definite integral

Definite Integral - IS (I)
Consider the integral $\displaystyle I=\int_{\frac{\pi}{4}}^{\frac{\pi}{3}} f(x)dx$ and the change of variable $x= \arctan(t)$. So $I$ comes equal to:
