## Homework Statement

Determine indefinite integral of

[tex]f(x) = \frac{1}{(x-1)(x-2)}[/tex] (1 < x < 2)

## The Attempt at a Solution

Use standard integral

[tex]\frac{1}{(x - a)(x - b)} = \frac{1}{a - b}ln\frac{x - a}{x - b}[/tex]

This doesnt give me the same answer as wolfram alpha or mathcad

Should instead treat this as a compound function?

[tex]f(x) = \frac{1}{(x - 1)}\frac{1}{(x - 2)}[/tex]
