`int _(-pi)^(pi) (cos^(2)x)/(1+a^(x)) dx, a gt 0`

The value of int_(-pi)^(pi)(cos^(2)x)/(1+a^(2))dx,a gt 0 , is

int_(-pi)^( pi)(cos^(2)x)/(1+2^(x))dx

Evaluate int_(-pi)^(pi)(cos^(2)x)/(1+a^(x))dx

The value of the integral int_(-pi)^(pi)(cos^(2)x)/(1+a^(x))"dx" , where a gt 0 , is - (A) pi (B) api (C) pi/2 (D) 2pi

If a gt 0 , then the value of int_(-pi)^(pi)(cos^(2)x)/(1+a^(x))dx is equal to -

Evaluate int_(-pi)^(pi)(cos^(2)x)/(1+a^(x)) dx.

int _(0) ^(pi) (cos ^(2) x ) dx,
