simple integral

u can write sinx + cosx as sin(x+pi/4) and then take x+pi/4 as t or any variable u feel like & then i think it will be possibe for u to do it....

its c/s+c = (c-s/c+s +1 )/2

integral of that is (ln(c+s) +x)/2 + C

plz post full solution

ive posted that only
c means cos
s means sin

Amit write ur question properly

is it

cosx or cos dx
