Hey Guys!
I'm stick on this question,
I know that the summation of n=0 to infinity for x^n/n! equals e^x
In the question it wants me to come up with a corresponding summation for the function x^2(e^(3x^2) - 1) … I don't know how to manipulate it to get the -1. I know i can substitute x for 3x^2 which would make my summation (3x^(2n))/n!. But I'm stuck after this point.
Thanks,
ISITIEIW
