Evaluate: int sqrt(cot theta) d theta

Evaluate: int sqrt(cot theta)dth eta

Evaluate: int sqrt(tan theta)d theta

Evaluate: int sqrt(tan theta) d theta

int_(0)^(pi) sqrt(2-2cos theta) d theta

Evaluate: int sqrt(tan theta d theta)

int(sqrt(cos2 theta))/(sin theta)d theta=

int(sin^(3)theta)/(sqrt(cos theta))d theta

Iff(x)=int_((x^2)/(16))^(x^2)(sinxsinsqrt(theta))/(1+cos^2sqrt(theta))d theta, then find the value of f^(prime)(pi/2)dot
