Learning Partial Integration: Step-by-Step Guide

[TheDestroyer]

Hi Guyz, Any one here can teach me the Partial Integration Step-by-Step?

I need to know every atom in the section, i tried to understand the previous written threads but didn't,

Thanks ...

Well, my first response would be that partial differentiation is no different from ordinary differentiation, with the other variables taken to be literal constants.

But I have to ask: How well do you understand ordinary differentiation?

Or do you mean 'integration by parts?'

Jeez, I didn't even notice that it said "integration". I saw "partial", and my brain just filled in the rest.

In that case, partial integration is usually taken to mean integration of a multivariable function over just one variable, with the others held constant.

So, Destroyer, is that what you mean, or do you mean integration by parts?

integral of 3xcosx dx is the problem.


3xsinx - 3cos x + C should be the answer base on the table.

Yes, ...

Yes I do understand Intergration and differentiation very well, i know how to get the derivative of anything, but because the integration is the opposite of differentiation, I'm getting some problems when trying to integrate some equation, especially I'm not in physics section, and i do need to make some researches on my own, hehehe

I just mean i want everything you know about intergration, and i would be very thankful for that :)
