`int_(-1)^(1)x*cos xdx`

(i) int_(0)^( pi/2)x cos xdx

Evaluate the following: int_(-1//2)^(1//2)cos x "log" (1-x)/(1+x)dx

int(1)/(1-cos 2x) dx

int(1)/( 1+cos 2x ) dx

If agt0 and A=int_(0)^(a)cos^(-1)xdx, and int_(-a)^(a)(cos^(-1)x-sin^(-1)sqrt(1-x^(2)))dx=pia-lamdaA . Then lamda is

The value of ({int_(-1//2)^(1//2) cos2x.log((1+x)/(1-x))dx})/({int_(0)^(1//2)cos2x.log((1+x)/(1-x))dx}) is

int_- 1^1x^(17)cos^4x dx=0

The value of the integral int_(-1//2)^(1//2) cos x log((1+x)/(1-x))dx , is

I=int_(0)^(1)tan^(-1)xdx

int_1^3 1/xdx
