Differentiating twice gives
Hi everyone,
I need to make the differential equation by eliminating the arbitrary constants a, b and c from ln y = ax^2 + bx +c.
I've done a similar problem (y=ax^2 + bx +c) using Wrosnkian and ended up with y'''=0.
Any hint to solve this problem? (e^lny = e^(ax^2 + bx + c) ---> y=e^(ax^2+bx+c)?)
