Homework Statement
Evaluate the integral
[itex]\int \frac{(a-x)^{r/s-1}}{(b-x)^{r/2}}dx[/itex]
Homework Equations
given: s>r
The Attempt at a Solution
I tried using a substitution:
let u=b-x
so du=-dx
this gives:
[itex]-\int \frac{(a-b+u)^{r/s-1}}{u^{r/2}}du[/itex]
I don't know what i should do after this, and i think this substitution will take me nowhere.
Does anyone have any ideas?
Thank you in advance.
