Hi all, trying to get "solve" to work with a function that has a "for loop"

The crux of the issue is this part. Is what I'm doing just not possible?

Plot that function first, then solve.
That will clarify the suite.

No problem from correctly dressed system.

Thanks for the attempt to help Jean, but I surmise from your answer that the particular construct I'm using, which involves a "sign" function, can't be solved using the "solve" function.

As shown in the attachment, the function does have a root.

I was suggesting a solve bloc within a for loop, your original question.
Cheers ... Jean

Sign isn't one of the problematic functions for solve (maybe for diff or int, but not for solve). Here is the problem: Mathcad have an special notation for the imaginary unit as 1i or 1j, SMath doesn't. Just change "i" by "n" under your Sigma:



Best regards.

Raznor - thanks for that! Appreciated.

I managed to solve it a slightly different way - rather than using the explicit summation form, I replaced it with a sum() call. So I didn't need to explicitly define the counter.

I have to stop trying to program like it's VBA
