I have this equation:

\(\displaystyle y'+ytanx=sinx\)

The integrating factor give me \(\displaystyle f=e^xcosx\)

Factor replacement and give me:

\(\displaystyle e^xcosxdy+e^xcosx(ytanx-senx)dx=0\) but the partial derivates give me:

\(\displaystyle Q_x=cosxe^x-senxe^x\) and \(\displaystyle Q_y=e^xsenx\)

Thanks

1- What is \(\displaystyle senx\) ?
2- I think if you read the title of your thread, you will know how to solve it ..
