1. The problem statement, all variables and given/known data Find coordinates of a piont on an arc from begining coordinates at the arc distance of 6.6821. Given Radius of 25 at (100,100), Begining coordinates at (125,100), Ending Coordinates at (115.6994,119.6301), with an overall arc length of 22.4472. 2. Relevant equations Newton's method, maybe? 3. The attempt at a solution I can think of a way to do it with trig, finding the chords between the end points and the length to the desired point then using the cosign law to find my angles, but I tried drawing this up in CAD as a check and my answer didn't match exactly. I can't figure out how to set it up using calculus methods.
