    thank you .
    There're both correct. 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 \cos^2(x)+K=(1-\sin^2(x))+K=-\sin^2(x)+K'

    using the identity \cos^2+\sin^2=1

    and that's all
