Homework Statement
Solve (x+2)sin y dx + xcos y dy = 0 by finding integrating factor mu(x)
Homework Equations
i put equation in standard form to get integrating factor
dy/dx + (x+2)sin y / x cos y = 0
but don't i need to get the y out of the sin and cos somehow?
so that y' + p(x)y = q(x)
I could simplify into dy/dx + (x+2/x)tan y = 0 but not sure if that even helps.
I am stuck please help, thanks
