y=int_(0)^( pi/2)sin^(4)xdx

int_(0)^( pi/4)sin^(4)xdx

Evaluate: int_(0)^( pi/2)sin^(4)xdx

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

int_(0)^(pi//2)sin^(9)xdx=

int_(0)^(2 pi)sin^(3)xdx

int_(0)^( pi)sin^(2)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 .

Prove that, int_(0)^(6pi)sin^(4)xdx=6int_(0)^(pi)sin^(4)xdx

If I_(1)=int_(0)^(pi//4)sin^(2)xdx and I_(2)=int_(0)^(pi//4)cos^(2)xdx , then

If I_(1)=int_(0)^(pi//4)sin^(2)xdx and I_(2)=int_(0)^(pi//4)cos^(2)xdx , then
