I have a question about the last integral; can you use Integration by Parts (since it's a product) or must it be integrated using substitution?

[@GlassofNumbers]

You can let u = 1 and dv = xe^(-x^2) dx and use substitution to find v.

[@GreenTornado]

@@GlassofNumbers Thank you. 😊

[@piqueras_]

I usually laugh at comments saying they have a final next day but this might be my case rn...

[@GlassofNumbers]

We all study hard before the final! Good luck on your final exam!!

[@mohan153doshi]

BTW, what does Glass of Numbers mean?

[@GlassofNumbers]

It means a glass with numbers in it 😁

[@mohan153doshi]

@@GlassofNumbers - as good as it gets.

[@promitaroychowdhury9678]

why 1/2 * e^-x^2 becomes zero after subsitituing with infinity?

[@sparr0www820]

Thanks a lot for your video, but could I say that the last integral is obvious because the function is odd

[@GlassofNumbers]

If the integral is not convergent, we can't use that property. The integral of x from -inf to inf is not zero even though f(x) = x is an odd function.

[@sparr0www820]

​@@GlassofNumbers That's right, thanks for reply. But I think this one in the video converges so we can use that... I'm not sure though
