Programming Challenge: a classic trigonometry problem

[peacecalc]

Hello all,

Original from Gerson W. Barbosa:

Quote:BTW the HP35s despite it's uselessness deals pretty well with this problem. After inputting the EQN:

SQRT(A^2 - X^2) - C / (1 - C / SQRT(B^2 - X^2))

and firing up SOLVE for X, it nicely asks for A, C & B and comes up with the answer in about a second or two.

Same as with 32s II. Oh, well these good old machines...
But only with a reasonable starting value for X, like 13.

Greetings
