Q$4$: Create a MATLAB script file to calculate the volume of a sphere:

$V=\frac{4}{3}{r}^3,$ where $r=0\mathrm{.}332m$

Q$5$: Create a MATLAB script file to plot the function $T=-6\mathrm{.}5lnt+8\mathrm{.}3t{e}^{0\mathrm{.}3t}$ over the interval $1t4.$ Put a title on the plot and properly label the axes. The variable $T$ represents temperature in degrees Fahrenheit, and the variable $t$ represents the time in seconds.

Q$6$ : Consider the following parametric functions:

$x=sin(t)(e^{cos(t)}-2cos(4t)-si{n}^5(\frac{t}{12}))$

$y=cos(t)(e^{cos(t)}-2cos(4t)-si{n}^5(\frac{t}{12}))$

Create a function in MatLab called myButterfly which accepts an array of numbers $(t)$ as input.

The corresponding array of $x$ and $Y$ coordinates should be the output, as described by the equations above.
