`int1/(1-sinx/2)dx`

int(1)/(1-sinx) dx

Evaluate : int(tan^(2)x)dx Evalauate: int1/(1+sinx) dx

Evaluate int(1)/(1+sinx)dx .

If int(1)/(1+sinx)dx=tan((x)/(2)+a)+b then

(i) int (cosx)/(1+cosx)dx , (ii) int (sinx)/((1-sinx))dx

int(sinx)/((1-sinx))dx=?

Evaluate: int1/(cosx-sinx)\ dx

Let f(x) = ln ((1-sinx)/(1+sinx)) , then show that int_(a)^(b) f(x)dx = int_(b)^(a) ln((1+sinx)/(1-sinx))dx .
