MATLAB Exercise $4$

Plot y $=$ sin$(2$x$)$ in red with a solid line and the Taylor polynomial approximation

z $=2$x $4$

$3$ x$3$ in blue with a dashed line for $\backslash$pi

$2<=$ x $<=\backslash$pi

$2$ on the same plot.

Hint: Use plot$($x$,$y$,$r$,$x$,$z$,--).$

Add a grid to the plot using the command grid on$.$

Type axis tight to set the axis limits to the range of the data.

NOTE: Use semicolon to suppress the output when you define the vectors x$,$ y and z$.$ Make sure

you use enough points for your graph so that the resulting curves are nice and smooth
