Re: Integral Calculus Problem

I suppose the second one.

Or simply e[sup]2x[/sup] will do.


X'(y-Xβ)=0

Re: Integral Calculus Problem

@Hast:  I'm terrible at Calc, but here's how I am trying to start.  May be wrong.
Oh, also, I'm not starting with the whole problem at all, just the exponential part of it for practice.


Use the letter U in place of x cubed perhaps, substitution?




What next I have to learn more.
Ignore this, see what reddog does next!!
