hammy said:I don't know why I can figure this one out.
I need to integrate ((x)^3)ln(8x)
using the form:
((u)^n)ln(u)du = (((u)^(n+1))/((n+1)^2))*[(n+1)lnu-1]+c
I just don't know what to make u equal to make the u/du substitution to match the form
hammy said:Aight, so now I can make it (1/8)u = x then just cube that and carry on?
