Hello Folks
I have integral
∫0π/2 (sinx/sinx+cosx) dx
I have got the answer is π/4
I have even solved indefinite integral
[ln(tan^2(x/2)-2(tan(x/2))-1)]/2 + [tan-1(tan(x/2)) + [ln(1+tan^2(x/2))]/2]/2
my problem is I am not getting pi/4 as final answer
I have got (ln(-2))/2 + π/8 + (ln(2))/4
is there something I am missing?
