Re: Solve this differential equation
Hi;
This is a Bernoulli equation and this exact problem appears in my text on p51! There is a standard substitution for it.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
