## anonymous 3 years ago Integrate the following: $$\large \frac{1}{\sqrt{2 \Pi}}e^{- \frac{u^2}{2}}$$

It doesn't have an elementary anti-derivative.

2. anonymous

hmmm so what wld the answer be?

3. anonymous

Find the Maclaurin series and then integrate that, if you want to make approximations.

4. anonymous

It looks like some sort of probability function.

5. anonymous

Nahhhh Forget it. Its stats so I will normalize it

6. anonymous

Thanks :)

you'll need to know gamma functions to evaluate that integral...

8. hartnn

that too if you have limits from 0 to infinity...that is definite integration

Actually its a normal distribution so I didnt realize but I had a table in the back of my book giving me the exact values :)
