Homework Statement
I'm reading Hinch's perturbation theory book, and there's a statement in the derivation:
...[itex]\int_z^{\infty}\dfrac{d e^{-t^2}}{t^9}<\dfrac{1}{z^9}\int_z^{\infty}d e^{-t^2}[/itex]...
Why is that true?
Because 1/t^9 for t in (z,infinity) is less than 1/z^9. Draw a graph.Homework Statement
