You have forgotten the constant of integration. If you include it then you can use a trig identity to go between answers.
Hello, Both of them are correct. There's just a matter of constant. A constant should be added to the two methods. But note that $\displaystyle \cos^2(x)+K=(1-\sin^2(x))+K=-\sin^2(x)+K'$ using the identity $\displaystyle \cos^2+\sin^2=1$ and that's all
ooo the constant......i was going a bit crazy there.......thank you for helping out guys ..thank you
