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

int_(0)^(pi//2) e^(x)((1+sin x)/(1+cos x))dx=

7. int_(0)^( pi/2)e^(x)((1+sin x)/(1+cos x))dx

int_(0)^( pi/2)e^(x)((1+sin x)/(1+cos x))dx=

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

int_(-(pi)/(2))^((pi)/(2))(e^(|sin x|)cos x)/(1+e^(tan x))dx is equal to (a) e+1 (b) 1-(pi)/(2)e(c)e-1(d) none of these
