Hello,
I am trying to solve a set of 4 equations for four variables by using this command:
Solve[{y1 == Sqrt[1  (x1  x0)^2/a^2]*b + y0,
y2 == Sqrt[1  (x2  x0)^2/a^2]*b + y0,
y3 == Sqrt[1  (x3  x0)^2/a^2]*b + y0,
y4 == Sqrt[1  (x4  x0)^2/a^2]*b + y0}, {a, b, x0, y0}]
Well, this takes a pretty long time as I found out, and I would like to know if it's worth the wait. Could you somehow estimate how long this calculation might take (just a ballpark figure, hours, days, forever because I did something stupid)? I tried it first with some numerical values for x1,y1... and it calculated in an instant.
I'm running the calculation on an Intel Core i52450M with 2.5GHz.
Thank you very much in advance for any guidance on this matter and all the best
Jens
