solving a complicated equation

[Shioris]

Hi, I have a problem. The equations goes like this,

Yn=TAN(x*T/2)-S/(x*D) where T, D, and S are user inputs. and n indicate nth root.

Then, 

delta = an equation that involves the summation of Yn

For now, I can make the user to input the Value of S to get delta. However, I need to make the program able to calculate S when the user know the value of delta. Do anyone any suggestion?

Thank you in advance

homework?

An equation that fits on a single line is not complicated. 😄

Are the values real or complex?

If you have a VI that calculates delta(S), and the function is well behaved, you could use Newton-Raphson to calculate S(delta).

And if the function isn't well behaved you can always whack it across the nose with a rolled up newspaper.
