Homework Statement
Find the general solution of the following differential equation:
x.(dy/dx) = y + sqrt.[(x^2) - (y^2)]
Homework Equations
I'm working through my excerise book and have been able to get through quite a few differential equations with success, but this one really does stump me. I think it's the sqrt.[(x^2) - (y^2)] that gets me confused.
The Attempt at a Solution
My first step was to divide both sides by x to get dy/dx alone, hence:
(dy/dx) = y + [ sqrt.[(x^2) - (y^2)] / x ]
This is where I begin to get lost. My natural instinct is to try and separate the x and y's but I can't seem to and the next step for is a mystery to me. I'm having a lot of troule identifying what sort of approach to use.
Any help would be very appreciated, thank you in advance.
