Homework Statement
Solve y^2*(1-(dy/dx)^2)=1
Homework Equations
The Attempt at a Solution
I expressed the ODE in terms of dy/dx and considered two cases. I got
(a) y^2 = 1 + (x+C)^2
(b) y^2 = 1 + (-x+C)^2 where C is a constant
However, my professor told me that there is another way to do this. He hinted me that this was some well-known ODE. Can someone enlighten me on where to find out more about this ODE? Thank you.
