[WP 34s] Trouble finding root  (solved)
Hello all,
I am having troubles finding the root of the following equation: \[0.05=\frac{x\times coth(x)  1}{10x\times coth(10x)  1}\] to which I created the following program: Code:
1 5 SLV 01 The 34s will complain there is a domain error. Hope I am missing something. Thanks Marcio EDIT: Found the error. Problem solved!

Indeed. Faster than the solver of the 35s too.

Code:
Gentlemen, I have been trying to solve this equation for X using the 15C but it is not working. Anyway, the code above will make the 15C output 0.0389, which is not correct. Could you identify what I am missing here? Please note that there has been no attempt to optimize the given code. Very much appreciated. Marcio
