Summary
Whether rate^2 + frequency^2 is not zero, which the closed form for an
exponential times a sine or cosine divides by: zero for a rate ofi times
the frequency, where the product is a sum of two exponentials instead.

Remarks
Symbolically as well as numerically. With a symbolic frequency f , the rate
-i f -- which is what A + i A tan(f x) leaves once written as
A e^(i f x)/cos(f x) -- gives -f^2 + f^2 , which
InnerSimplified does not collect, so the evaluation is not a
number and the guard passed: the answer then divided by a zero it could not see and
wasNaN at every point.
