Nyquist limited versions of trigonometric functions added

[zunzun.com]

I have added Nyquist Theorem frequency-limited versions of several trigonometric equations to the zunzun.com web site, these are in addition to the existing equations which were unchanged. Because a sufficiently high-frequency sine wave can be made to pass through most data sets regardless of the actual data shape, these new equation versions calculate a maximum frequency based on Nyquist's Theorem in order to mitigate the problem of incorrect high-frequency results - this is particularly useful when function finding.

To install the additional equations, use the command "python3 -m pip install -U pyeq3" (without quotes) at a command prompt. Please let me know if you have any questions.
