I need to integrate from 0-t. I am told to set u= Erf and u'= (2e^-x^2)/pi^1/2. v' is 1 and v=x.
i am also told that the answer is t Erf(t)+ ((e^-t^2)-1)/pi^1/2
how many times do I need to integrate by parts to come to that answer? It gets more complicated to me each time I integrate, no matter which assignments I use. Can I somehow do it keeping the Erf designation or do I need to use the actual function (which they didn't give in this assignment.)
