`int (dx)/(1+sinx)=tan(x/2+a)+b` then find the values of `a` and `b`

int(dx)/(1+sin x)=tan((x)/(2)+a)+b then find the values of a and b

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

If int(dx)/((1+sin x))=tan((x)/(2)+a)+b , then the value of -(2048a)/(pi) must be

If the value of int_0^pi(x/(1+sinx))^2dx=lambda , then find the value of the integral =int_0^pi[(2x^2*cos^2(x/2))/(1+sinx)^2]dx

If tan A=(a)/(a+1) and tan B=(1)/(2a+1) then find the value of A+B
