Using MATLAB, plot a sine function, $sin(t),$ where $$ is the frequency of oscillation. Do the followings.

$(1)$ Create a time vector, $t,$ from $0$ to $5s$ with a time interval of $0\mathrm{.}2s.$

$(2)$ Create an output vector of $sin(3t)$ using the time vector, $t,$ created in $(1).$

$(3)$ Create another time vector from $0$ to $5s$ with a time interval of $0\mathrm{.}02s.$

$(4)$ Create another output vector of $sin(3t)$ using the time vector created in $(3).$

$(5)$ Plot the two output vectors created in $(2)$ and $(4)$ together in the same figure. Use a legend to identify those two curves.
