Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

I have a complicated equatation :

K1=tan(K2*x)/tan(K3*x)

since i can not solve it for 'x',

i tried using the Microsoft Exell feature : Tools --> Gool Seek ,

but this method does not work for some values for the coeficients.

Could someone provide link to free software,

solving that kind of equation by approximation ?

p.s. i saw this section of the forum is not for such questions, so

mods may move my subject if deemed necessery
