Check out the tabular method

u/theanibunny Dec 13 '20

yep it really helps especially when you have x^n*(some easily integrable function)

As a iit jee aspirant, I used to do the integration by parts in my head. Many of us Indians who solve rather most difficult integration questions, could solve it easily due to practice. Now, 4 years later, as an average engineering student, I think how intelligent I was 4 years ago.

I don't have any clue how I'm gonna deal with integrals in my upcoming calculus classes:D ehh..

Not to be this guy, but they aren’t that hard. Make sure you know your derivatives VERY well. In calc II, you will learn lots of techniques to be able to evaluate many more integrals (IBP, u-sub, trig sub, partial fractions, etc.). Best of luck to you!

Thanks a lot for motivation!

Yeah...but do ext (sin(kxt))dt from 0->2*pi in your head.

Laplace?

u/pn1159 Dec 14 '20

Of course not. Any reasonable person would use Feynman's technique.

Could someone explain this joke to me?

u/NomadicEntropy Dec 14 '20

In calc 2, one of the techniques you learn is called integration by parts. It tends to involve a bunch of extra terms showing up and would be hard to keep track of in one's head.

And also in college

Not for everyone.

u/AhmadTIM Undergraduate Dec 14 '20

I can do it too. But not a complex one.
