1. ## Help:(solving diff. eq.)

Hi
how can I solve this problem:
(y^2)y'=a.(x^1/2)+b.y
a & b are constant and I don't know anything about a and b(I mean the range and ...).
I solve this with MATLAB and MAPLE but they didn't give good answers.

Try to use this substitution $\displaystyle{y=\sqrt{x}\,z~\Rightarrow~y'=\frac{z }{2\sqrt{x}}+\sqrt{x}\,z'}$
