I am relativity new to this software. I am trying to do a harmonic derivation of a signal passing through a transistor's transfer function.
One step requires reducing a term such as,
(A Sin (wt) )^3
to first order sine's and cosine's. Doing it by hand it should look something like
a Sin(wt) - b Sin(3wt) + c Sin(wt)
How can this be done in Mathematica? I have tried using functions such as TrigReduce but can't seem to get any of them to give the right result. So I am a little lost atm.
Thanks for any help.
