### Re: 1203: "Time Machines"

I assumed that the trouble with this time machine is that it only sends you forward in time, at a rate of 1 second per second.

### Re: Simple (probably) triangle problem (need help)

OK, my current implementation doesn't really work, the calculated distance jumps around all over the place. I uploaded a video to YouTube so that people can see the behaviour and possibly recognise it: http://youtu.be/f0eecwpexS4 I made it so the 2 points of the triangle rotate at different speeds ...

### Re: Simple (probably) triangle problem (need help)

The only information available are the measurements marked on the diagram and I need to know the length of the line marked in bold. Any of the co-ords maybe be negative. Either angle may be the larger. Let P2x = v * cos(a1) P2y = v * sin(a1) P3x = tx - x P3y = ty - y then the distance you want is d...

### Re: Simple (probably) triangle problem (need help)

I'd solve it using a vector method, myself. If we find a vector going from p1 to p2, or p1 to p3 and take the scalar product of that vector with one of length 1 in the direction of the line you want, you get the length of that line. (To be more precise, this finds the length of the lines projected ...

It's probably not homework, but I'll put it in a spoiler. If it is homework, don't go far with the angles and lengths, think how you can get the coordinates of the intersection with the known data. Assuming p1(x1,y1),p2(x2,y2),p3(x3,y3) 1. Get the equation of the line p2,p3:...
