anyone know how you integrate e^3x^2/2?

that is, e all to the power of 3x^2 divided by 2.

Oh, hmm, try u = x²? When you differentiate you'll get rid of the 2?

Scrap that.

So its

I don;t think it would be right but just differentiate the then use chain rule idea to bring it before e, and after e if yoy get that at all?

We need Max/TTO/jenni

You could try splitting it up into (e^x²)^(3/2) (can't use Latex )?

I just managed to get the correct answer

was the differential equation dx/dt + 3x = e^-t

I've not got as far as using diffential eqs in integration

anyway back yoto work, gonna be late
