int(sin^(2)x+45int_(0)^( pi)(xdx)/(a^(2)cos^(2)x+b^(2)sin^(2)x)=pi

int_(0)^(pi)(xdx)/(a^(2)cos^(2)x+b^(2)sin^(2)x)=(pi^(2))/(2ab)

Evaluate int_(0)^( pi)(xdx)/(a^(2)cos^(2)x+b^(2)sin^(2)x)

Evaluate int_(0)^(pi)(xdx)/(a^(2)cos^(2)x+b^(2)sin^(2)x)

Evaluate int_(0)^(pi)(xdx)/(a^(2)cos^(2)x+b^(2)sin^(2)x)

Evaluate: int_(0)^( pi)(xdx)/(a^(2)cos^(2)x+b^(2)sin^(2)x)

Prove that int_(0)^(a) f(x) dx = int_(0)^(a) f(a - x)dx and hence evaluate the following: (f) int_(0)^(pi)(xdx)/(a^(2)cos^(2)x + b^(2)sin^(2)x)

Evalute : int_0^(pi)(xdx)/(a^2cos^2x+b^2sin^2x)

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

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