 Apr23 comment How to solve a problem in relative motion? I know how to do recursive by hand, and I've programmed Euler before. I can't figure out how to do this particular recursive.

The range of angle that the person can jump off and land in the boat, or the time when the person can jump off and land. If I can get one, then I can get the other. Apr23 comment How to solve a problem in relative motion? From the looks of the previous assignments, I can use numerical techniques but I'm not sure if I can use the quadratic equation. Here is what he said: "For this project, use recursion techniques to find your solution. You may use analytical equations to check your answer, but your program must find the solutions through recursion techniques." Which brings up the question, how would I solve for 0 without using quadratic solving? I can't think up of a way. Apr23 comment How to solve a problem in relative motion? The instructions are to use recursive programming, which is the root of all evils in this problem. I can reduce the problem to series of equations and solve them analytically, but I can't use analytical commands. I'm not sure if Solve[] is analytical... But your version is certainly better than what I could come up with. Thank you for your help. Apr23 comment How to solve a problem in relative motion? What I'm trying to do is: calculate the landing point for the person at each increment, then calculate the location of the boat at that time. If the person's location=boat location, then output the time the person left the wheel, if not, go to the next increment. Apr23 asked How to solve a problem in relative motion?
