Question

(ye^xy-1/y)dx+(xe^xy+x/y^2)dy=0
not sure if these are exact or not. if they are im going to need help with this problem for sure. i don't think they are BTW

Answer 1

i got
\[\delta M/\delta y=e^{xy} and \delta N/ \delta x=e^{xy}+1/x\]

Answer 2

so you have to find dy/dx?

Answer 3

no its differential equations problem. i have to prove that they are exact and if they are solve the problem

Answer 4

let me think...this is a bit more challenging then the other questions i have been doing

Answer 5

\[M=(ye^{xy}-1/y) and N=(xe^{xy}+x/y^2)\]
then you take the partial derivative of each. partial m with respect to y and N with x

Answer 6

right?
