seems like you can simplify this by using a bit of algebra and a definite integral theorem (maybe its a theorem, im not quite sure):

$$ \int_{a}^{b} f(x) dx = \int_{a}^{c} f(x) dx + \int_{c}^{b} f(x) dx $$

the second integral, if we factored out a -1 and took it to the outside, it would be the same function as the first.  maybe that'd help fix it up a bit
