Question

can anyone help me?????
xy' - 2y-x^3sinx = 0

Answer 1

do i use homogenous equation or 1st order or exact?

Answer 2

divide through by x

Answer 3

move the x^2 sin(x)
you'll get y' +f(x)*y = g(x)

Answer 4

that should be familiar:)

Answer 5

oh i see ! 1st order!! but are you able to use homogenous equation? is that possible?

Answer 6

It's in the 'form' where you can use the 'integrating factor' method... I think I remember you referring to that as 'exact' but I'm not sure on that..

Answer 7

different people call it by different names, but we did it once before, iirc.

Answer 8

Do you know what I'm talking about?

Answer 9

oh i see okay! so basically try to do make it into the formula form and see if it works and use that integrating method.
