# How to manipulate this expression?

1. Mar 31, 2008

After solving a DE by Laplace I was left with

$$\frac{1}{s^3}$$

Now I have a formula for $$\frac{n!}{s^{n+1}}$$

which could be $$\frac{2}{s^{2+1}}$$

Now if I just multiply the $$\frac{2}{s^{2+1}}$$

by a factor of 1/2, is that the same same as my original?

Sorry if this is a stupid question.

Yes.
And I think someone once said that there are no stupid questions.
Cheers.
