Solver Problem 'Maybe'
Below is the equation for a Circle.
R^2=(XH)^2+(YK)^2. The solver will solve for R=7.2801. X=4, H=2, Y=6 and K=1 R^2=53. You can solve any of the variables except 'X'. Solving for X returns '0'. Rearranging the formulae to solve for X. Note: SQRT below instead squareRoot sign on calculator. X=H+SQRT(K^22*Y*K(R^2Y^2)). Note: 'H+' Now I can solve for any variables including 'X'. 2+2=4 Of course using X=HSQRT(K^22*Y*K(R^2Y^2)). Note: 'H' cannot solve for X either, since SQRT(K^22*Y*K(R^2Y^2))=2. 22=0 Which may be a clue????? Its seems that the Solver precedes the SQRT sign with H instead of H+ and returns '0' instead of '4'. The other option is, maybe I've had too much to drink over the Holidays. Thanks BM

Solving for X works on my prime. What version softwear are you running? The solver app in one of the earlier versions had issues.

Hardware ver. C. on Does not work on the Mac VC either. with ver. 11226. X Returns 3.599E5 Same problem on the Windows VC. X returns 3.599E5. ver. 11226 Thanks for your reply. BM

Put in a guess for X closer to 4 and it should work. The equation has 2 roots, X=0 and X=4; which one you get depends on the initial value of X.

Thanks Nigel Should have thought of that, I'll blame that one on 'Lipitor", Read the book 'Lipitor the thief of Memory' BM
