Is there any way to make this equation work on the HP 50g?
I'm writing a simple program in my 50g to be able to get the frequency response of a electronic lowpass filter. The equations are pretty simple to understand, so I decided to try and write a simple program and this is what I have come up with:
Code: %%HP: T(0)A(D)F(.); The problem is that when I run it I get the following message "ISOL Error: Not reducible to a rational expression". I know this is because of the limitations of the solver in the HP 50g, but is there any way to make this work?

RE: Is there any way to make this equation work on the HP 50g?
I just tried something similar in my HP Prime and I was successful by running the same equation through the fsolve function like this:
Code: fsolve(fs,f,0..30000) And I was able to get the answer, 1587.77482493 in this case. Is there a equivalent solver function in the HP 50g where I can put a range of guesses?
