Draw an amplitude modulated wave with an equation.

Explanation

where, `y=(A_c+A_m sin omega_(m)t) sin omega_(c)t`.
`y= c_m(t) = (A_c+A_m sin omega_(m)t) sin omega_(c)t`
`A_c` - amplitude of carrier wave as in
`c(t)= A_c sin omega_(c)t " and "m(t)= A_(m)t` which is a modulating signal wave
and `omega_(c) = 2pi f_(c) " and "omega_(m) = 2pi f_(m)`.
