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

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)

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

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

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)
