but dont u anti derivavtive the force of interest formula to get a(t), u are also given the time which is 1 and 11 years

1) No, you don't "anti derivative" anything, since that isn't a verb. It requires an integral.

2) I cannot see the gif you attempted to display. Can you write it out? - Oct 3rd 2008, 11:37 AMactsci231
force of interest = 0.0245(1 - 0.007 t) ^(-1)

Well, there you go...

$\displaystyle \int_{0}^{11}\left(\frac{0.0245}{1-0.007t}\right)\;dt = A$

$\displaystyle 500 \cdot e^{A}\;=\; ??$

Why are you struggling with this? Do you have enough calculus background to handle the integral? Better brush up.

Note: You should also work on using whole words and complete sentences. That WILL improve your presentation. - Oct 4th 2008, 06:25 AMTKHunny
Odd. I can now see the gif. It must be a firewall thing on my other PC.
