I'm trying to do something very simple...
I'd like to have a sine function, where the frequency is controlled by a separate frequency function
Something like this:
g(t) = sin(2*pi*f(t)*t)
Assume that
f(t) = 20*exp(-2*t)+4
I would expect a sine wave that starts at 24 Hz and then slowly slows down to 4 Hz.
But when I plot it, I get some strange results for t in [0.5, 2], see attached image. The frequency for those values is very low. How's that possible? Is it my plotting program that acts funny? How can I get the expected (described) behaviour?
Thanks in advance!
