if its a special kind of equation, we can up one side, and then down it to the other to fill in some missing parts
if M(x,y) dx + N(x,y) dy and My = Nx, then we have a condition is suitable
they are not equal. the M=(3y^2)cosx - 1 and N=1
what methods are available to you to work the problem with?
this question needs to be solved using the integrating factor by following the instructions in the worksheet. but I think I can use homogeneous coefficient if I still can't answer it
This will probably help you understand integrating factor a little better, check it out then let us know if it makes any more sense http://mathworld.wolfram.com/IntegratingFactor.html
that sub doesnt work
hmmm can u think of and substitutions to make it separable
we have to be able to get it in that dy/dx + p(x) y=g(x) form if u want to use integrating factor
wolfram has confirm non lin equation, nothing we can do then
wolfram has all the built in bernoullis tricks so
it can't be solve?
hmm... did you copy the eq correctly?
this yea? \[((y^3)cosx - y)dx +(x+y^2)dy = 0\]
