Homework Statement
[tex]\int[/tex][tex]\frac{13}{(x-8)^2}[/tex]dx
Homework Equations
it is integrated from 7 to 9 and i am aware that there is an infinite discontinuity at x=8 so we have to take the limit from both sides individually.
The Attempt at a Solution
The only thing I can think that I might be doing wrong is just integrating it wrong but it seems like such an easy integration. The integration that I come up with:
-[tex]\frac{13}{x-8}[/tex]
as a goes to 8 [[tex]\frac{-13}{a-8}[/tex]+[tex]\frac{13}{7-8}[/tex]]+[[tex]\frac{-13}{9-8}[/tex]+[tex]\frac{13}{a-8}[/tex]]
and this comes out to be -26 which has to be wrong because the graph is above the positive x-axis and also it is not one of my answer choices.
