e = abs(sqrt((a - x)2 + (b - y)2) - sqrt((c - x)2 + (d - y)2))
How can I solve for y if all other variables are known.
Hope that makes it clearer. I assumed a trigonometric solution was the way to go.
I'm not sure how trigonometric functions would apply to the solution methods for this algebraic equation. The solution would likely start by squaring both sides (which will eliminate the absolute value), simplifying, isolating the remaining radical, and then squaring again.
