int cos x^(0)dx=

underset equal to int(cos x)/(x)dx=(pi)/(2) then int_(0)^(oo)(cos^(3)x)/(x)dx is

Prove that int_(0)^(pi//2) (sin x -cos x)/(1+sin x cos x)dx = 0 .

int_(0)^( pi)|cos x|^(3)dx

int_(0)^((pi)/(2))(x sin x*cos x)dx

int_(0)^((pi)/(2))(x)/(sin x+cos x)dx

int_(0)^( pi/4)(sin x-cos x)dx

True or False: underset0 overset(pi)int cos^5 x dx ne 0

Prove that int_(0)^(a) f(x) dx = int_(0)^(a) f(a-x) dx . Hence, evaluate int_(0)^(pi//2) (sin x - cos x)/(1+ sin x cos x) dx.

int_(0)^(pi) cos^(8) x dx=
