A-Level Maths: H5-28 Further Integration: When Integration by Parts goes Right

[ThePlazmapower]

As someone in the final year of undergraduate engineering at uni, I have to keep referring back to this video to refresh me on integration by parts, since the lecturers typically explain the process vaguely or come up with the excuse that it's trivial.

Integration by parts is required in my steps; to calculate the deflection of a uniform axially loaded cylinder as part of structures, which is for my CW.

I really express my gratitude for your teaching sir!

Much obliged - Rizwan

I’m my first year physics degree and this helped refresh my memory a lot as I’m a mature student thank

Hi,

lets say you want to integrate (12x^2)(3+2x)^5, which one would you equal to u. Both go under algebra in the LATE rule. So is this one of the cases where it doesn't matter what u equal to u ?

Thanks

When integrating dv/dx, why don’t we add a constant of integration as it is not a definite integral? For example, why isn’t v=e^x + c?

HI, I am really stuck on an integration question as I have done the integral and I have got to the equation e^b-e^-2b-e^2+e^-4=0, and I have no clue in hell how to solve it. I put it in my classwiz and it got an answer of 2 but idk how to work it out. Any help would be appreciated, thanks.
