Basic Matlab Plotting:

Use Matlab to create the following single plot with three subplots. All titles, gridlines, and axis labels should be

as shown.

Notes:

Each subplot must have the shown title and any axis labels shown$-$spelling will matter.

Hint: The Matlab help on subplot shows how to get one plot to extend across two columns.

The first subplot is an arc, centered at $(3\mathrm{.}5,-2),$ with radius $=1\mathrm{.}5,$ extending from $450$ to $2250$ from

the positive x$-$axis. Use a similar method as previously used to generate $100$ pairs of $($x$,$y$)$ data for

a whole circle that is easy to modify to go between two angles. Also plotted is a $+$ sign at the

center of the arc $($created using plot$(),$ not text$()).$ Note that the axes have equal scaling $($so the arc

Notes:

$-$ Each subplot must have the shown title and any axis labels shown$-$spelling will matter.

$-$ The first subplot is an arc, centered at $\backslash ((3\mathrm{.}5,-2)\backslash ),$ with radius $\backslash (=1\mathrm{.}5\backslash ),$ extending from $450$ to $2250$ from the positive $\backslash ($ x $\backslash )-$axis. Use a similar method as previously used to generate $100$ pairs of $\backslash (($x$,$ y$)\backslash )$ data for a whole circle that is easy to modify to go between two angles. Also plotted is a $+$ sign at the center of the arc $($created using plot$(),$ not text$()).$ Note that the axes have equal scaling $($so the arc is circular and not squished$)$ and they extend at least $0\mathrm{.}5$ past where the circle containing the arc would be $($xlim$|$ and ylim$).$

$-$ The second plot is response $\backslash (=1-\backslash$exp $(-\backslash )$ time$),$ plotted from $0$ to $10$ with blue dash$-$dot lines. Note the title and axis labels. Set the $\backslash ($ y $\backslash )-$axis limits such that the lower limit is clearly below the lowest part of the curve.

$-$ The third is two curves: $\backslash ($ p o s$=-2\backslash$cos $3$ t $\backslash )$ and vel $\backslash (=6\backslash$sin $3$ t $\backslash ).$ The subplot uses the whole plot width. There must be axis labels, a legend positioned as shown, and the LineWidth of both curves is $2$ for better visibility.

Some of the functions you will use are also in the PDF handout available on CatCourses.
