### Re: Numerical Integration Help!

It's a presentation on my senior project. I'm simulating multiple charged particles, and I have the net force on each particle, the location of each particle, and the current velocity of each particle. So to minimize the error on the displacement of each particle for every calculation of position, I...

### Numerical Integration Help!

I have a presentation for tomorrow, and I need to explain why the Runge-Kutta (RK) method for numerical integration is more accurate than Euler's method. Can someone help me?

### Re: Recommend a book

I would recommend the Temeraire Series, by Naomi Novik. The series is basically the Napoleonic Wars with dragon aerial combat. It is pretty neat.

Also, anything by Douglas Adams or Terry Pratchett. Those two are pretty much the sci-fi/fantasy authors that any nerd will like.

Oh, wait! Now I remember what he actually said. It wasn't that [imath]\lim_{\theta \rightarrow 0} (sin(\theta)) = \theta[/imath]. It was that [imath]\lim_{\theta \rightarrow 0} (sin(\theta)) = \lim_{\theta \rightarrow 0} \theta[/imath]. That makes everything make more sense!
