int_(0)^((pi)/(2))sin^5 xdx= .

Prove that int_(0)^((pi)/(2))sin^(3)xdx=(2)/(3)

Prove the following int_(0)^((pi)/(2))sin^(3)xdx=(2)/(3)

Show that, int_(0)^(pi)sin^(3)xdx=2int_(0)^((pi)/(2))sin^(3)xdx and hence, find the value of int_(0)^(pi)sin^(3)xdx .

int_(0)^((pi)/(2)) sin^7 xdx is :

int_(0)^( pi/2)sin x*cos^(3)xdx

Show that, int_(0)^(pi)sin^(4)xdx=2int_(0)^((pi)/(2))sin^(4)xdx , hence, find the value of int_(0)^(pi)sin^(4)xdx .
