Is there a mathematical formula for and arrows trajectory? I have used Jackson archerys but it isn't what I am looking for. Is there another place to figure trajectory or a formula to figure it??? I would think it would be to complex for a formula to take into account for all the determining factors of trajectory.

Its winter and I am bored

This should keep you busy for a while:

She plans to add discussions that consider drag as well in the near future, hehe.

My brain is rattled after reading that page. Thats a little to complex for my likeing. Thanks though.

Any other sites or not so complex formulas?

Here's a link to Andrew Middleton's Graphing Trajectory Calculator. It runs in a Java applet, so be sure you've got Java running.
