1) solve the given differential equation by separation of variables?
2) solve the given differential equation by separation of variables, give an explicit solution?
x2dy=(1-x2-y2-x2y2)dx
Solution
1) Key here is to separate the e(x+2y) into two by using the power rules.
e(x+2y)=(ex)(e2y)
Then cross multiply and divide and you get:
ye2ydy=xe-xdx
Now integrate by parts on both side and you should get
(1/2)ye2y-(1/4)e2y=-xe-x-e-x
