In general, if r is the distance from the origin, and is the angle from the positive x-axis, then the endpoint is .
I've got a question which I'm hoping someone can answer for Me.
if I have the x/y coordinates of the start point of a line (i.e. 0,0),
the angle of the line (i.e. 45 degrees),
and the length of the line (i.e. 10);
how do I calculate the end point of the line?
I'm sure its a pretty basic problem, I just don't have a clue how to go about it.
