Homework Statement
(2x-y)dx+(2y-x)dy=0 y(1)=3
solve the given initial value problem and determine at least approx where the solution is valid?
this should be simple right? I got 2y+2x=C and then 2y+2x=8. It doesn't match the answer in the back of the book at all, and I do see how they could have gotten the answer in the back. Is my answer right? The book says y=[x+sqrt(28-3x^2)]/2, abs(x)<sqrt(28/3)? or is the book right, and if so how do you get to their answer?
