A forced harmonic oscillator with a circular frequency ω = 6.283 s⁻¹ (frequency ν = 1.000 s⁻¹) is exposed to an external force F₀ sin (αt) with circular frequency α = 7.540 s⁻¹ such that in the solution of Eq. (12.63) becomes

z(t) = sin(ωt) + 0.100 sin (αt).

Using Excel or Mathematica, make a graph of z(t) for a time period of at least 20 s.
