int_(pi/4)^( pi/2)Cot x*dx=

solve int_(pi/4)^(pi/2) x^2 dx

Evaluate: \int_(pi/4)^(pi/2) cot^2 x dx

int_(pi//4)^(pi//2)cot^(2)x dx =

I_(n)=int_(pi/4)^(pi/2)(cot^(n)x)dx , then :

int_(pi/4)^(pi/2) (cot^(4)x + cot^(2)x) dx =

int_(pi//4)^(pi//2)(e^(cot x))/(sin^(2)x)dx=

Statement-1: int_(0)^(pi//2) x cot x dx=(pi)/(2)log2 Statement-2: int_(0)^(pi//2) log sin x dx=-(pi)/(2)log2

int_(0)^(pi//2)x cot x dx=(pi)/(2)(log2)
