revised Simple numerical methods for calculating the digits of $\pi$
fixed mathjax typo; please don't put mathjax on plain old numbers.

comment Simple numerical methods for calculating the digits of $\pi$
that's easy: since the arctangent is a power series, convergence is dictated by the largest argument to the arctangent. In my case, it's 2/11.

comment How to move a body to a point using only velocity?
NJGUY: you still need to clarify your question. What do you mean by "move" ? Are you writing software to display something at certain points in time? Or do you just want to know the velocity (vx, vy) required to get an object from point (x1,y1) to point (x2,y2) in some time T?

The writeup in Wikipedia of Bresenham's algorithm seems more complicated than it should, and also seems like it does not handle lines with steep slopes very well. This really shouldn't be that complicated. We also don't know whether NJGUY wants to draw individual pixels (in which case Bresenham's algorithm is a good match) or just wants to calculate an object's position at various positions in time. Whether you call it vector algebra or two parametric equations x = fx(t), y = fy(t), I still think it's simpler than trying to use time-independent algorithms.

@RobertHarvey: no, you don't need the slope if you are using vector algebra.

Please clarify your question. Is the second body's position fixed?

mathjax is not needed for this simple an example.
