Use Matlab to generate code. Please post Code and Graphs

Generate and plot the signal represented by $x_{5}u(t)=e^{-0\mathrm{.}1t}.**sin(2\frac{t}{3}),$ for $t$ ranging from $0$ to $30$

in $0\mathrm{.}1$ increments. Use proper axes labels with title.

Generate and plot the signal represented by $x_6(t)=sin(4t)\frac{.}{4}t,$ for $t$ ranging from $-1$ to $1$ in

$0\mathrm{.}001$ increments. Use proper axes labels with title
