Hello,

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.
