Here's a pretty difficult integral that our prof threw at us a couple days ago... left the whole class a little dumbfounded. I wish I had symbols to use (such as the ones that a lot of the pros on this site use)... but I'm sure you'll be able to understand.(adsbygoogle = window.adsbygoogle || []).push({});

Integrate (from a to b) the following (1-x^2)(f ''(x)) dx

He went on to say that if we couldnt get that, perhaps we should look at this one:

Integrate (from -a to a) the following (a^2-x^2)(f ''(x))

(he suggested IBP)

I think what threw most people off was how he knew what f''(x) was without identifying it directly.

Thanks for everyones help in advance!!
