AM = k*(1+f(t))*cos(w*t+theta) Eqn. 1

where k is the desired carrier amplitude
f(t) is the modulating signal, scaled so that negative peaks are
greater than -1
w is the radian carrier frequency
t is time
theta is whatever carrier phase offset you want; a constant.

Now you go figure it out. Is there anything in your incomprehensible
problem statement that can't be accommodated by Eqn. 1? Actually
accomplishing it is left as an exercise for you to spend the rest of
your life on.
