# integrating factor of linear equation watch

1. I wanna obtain the differential equation form the equation (sin x -xsiny )dx - (cosy +ycosx) dx... my integral R(x) and R(y) correct ? why it look so complicated ?

2. I think a bit more effort in formulating your question and a scan of the original question will help generate answers.

FYI "(sin x -xsiny )dx - (cosy +ycosx) dx"

Is not a question.

If this is correct then you are correct ... but I cannot see the original question
(yesterday you copied the question wrong)

the original question is (sin x -xsiny )dx - (cosy +ycosx) dx , what's wrong with my working ?
