Q.int_(0)^( pi)(e^(cos^(2)x)(cos^(3)(2n+1)xdx,n in I

Evaluation of definite integrals by substitution and properties of its : If n is an integer int_(0)^(pi)e^(cos^(2)x)cos^(3)(2n+1)xdx=............

For any integer n, the integral int_(0)^( pi)e^(cos^(2))cos^(3)(2n+1)xdx has the value

For any integer n, the integral int_(0)^(pi)e^(cos^(2)x)cos^(3)(2n+1)xdx has the value a) pi b)1 c)0 d)None of these

If n is an integer then the value of int_(0)^(pi) e^(cos^2x)cos^(3) ((2n+1)x)dx=

int_(0)^(2 pi)cos^(7)xdx

int_(0)^(2 pi)cos^(4)xdx

The value of int_(0)^( pi)e^(sin^(2)x)cos(2n+1)xdx=

For any value of n in Z , int_(0)^(pi) e^(cos^(2)x) cos^(3) [( 2n +1) x ] dx is
