Homework Statement
Specifically what i don't understand is a situation where you can't get the equation in the standard form of y' + p(x)y = q(x)
the integrating factor is e^integ p(x), but what if y is part of a sin or cos, as in this equation:
(x+2)sin y dx + xcos y dy = 0
if i rearrange so that it is: y' + (x+2)sin y / x cos y = 0, it still isn't in standard form.
So at that point how am i supposed to proceed? What step do i take to get the integrating factor?
So, if equation isn't separable, and isn't exact, and can't be put into standard form, how do you solve it?
thanks for any help
