Hi sweet

I think it's better if you type your question here. If you don't know how to type it, you can learn it here : http://www.mathhelpforum.com/math-he...-tutorial.html

I'll help you this time to type your question.

$\displaystyle \int_0^{t}\frac{du}{1-\frac{\delta - a}{2\delta}e^{(\delta - a)u}}$

What are $\displaystyle \delta$ and a? Are they independent of u ? - Sep 10th 2009, 05:09 AMsweet
thank u songoku (Itwasntme)

about $\displaystyle \delta $ and a ,they are a constant .. - Sep 10th 2009, 05:21 AMsongoku
Hi sweet

So, in order to simplify the integral, we can write:

$\displaystyle \int^t_0\frac{du}{1-pe^{ru}}$ , where p and r are constants

You can :

1. multiply the integral by $\displaystyle \frac{e^{-ru}}{e^{-ru}}$

or

2. write the numerator as 1 - pe^(ru) + pe^(ru)
