Question

how can i tell if xe^(-x^3/3) from 1 to infinity converges or diverges?

Answer 1

you mean the integral of?

Answer 2

first find lim f(x) as x-> infinity

this will tell you if the graph is bounded(converges) or unbounded(diverges)

Answer 3

If it converges is there a way to find where it converges?

Answer 4

numerical analysis... I am assuming this antiderivative can't be done
