Plot the sum of the two non$-$synchronized simple harmonic motions in Octave $($or Excel$).$

Print out and attach your plots to this assignment. $(2$ marks each$)$

a$)y_1(t)=2sin(5t)-1\mathrm{.}5cos(5\mathrm{.}1t)$

b$)y_2(t)=2sin(5t)-1\mathrm{.}5cos(20t)$

c$)$ Explain the difference in the resultant motion between the plots you created in parts

a and b$.$
