"Question $3$: Plotting multiple lines.

$3\mathrm{.}1.$ Under the section write a script that plot two sine waves on the same plot.

$$ Create a time vector t from $0$ to $2$ with enough samples t XC$02$ o get smooth lines

$$ Plot $1=2$sin$()$ with a dotted red line

On the same plot, plot y$2=()$ with a dashed black line.

$$ Label the x$-$ axis

$$ Label the y$-$axis

$$ Give the figure a title

$($use MATLAB and mfile format$)"$
