Exercise $2$

Use the linspace command or the colon operator : to create a vector $t$ with entries

$2,2\mathrm{.}1,2\mathrm{.}2,$dots,$10,$ and define the function $y=\frac{e^{\frac{t}{15}}cos(2t)}{0\mathrm{.}6t^2+4}($make sure you use $"$;$"$ to suppress the

output for both $t$ and $y).$

$($a$)$ Plot the function $y$ in black and include a title with the expression for $y.$

$($b$)$ Make the same plot as in part $($a$),$ but rather than displaying the graph as a curve, show the

unconnected data points. To display the data points with small circles, use plot $(t,y,{?}^{\text{'}}{o}^{\text{'}}).$

Now combine the two plots with the command plot$($t$,$y$,\text{'}$o$-\text{'})$ to show the line through

the data points as well as the distinct data points.
