Consider a model for the wind chill temperature as a function of the actual air temperature and the

wind speed. This model is curve fitted from several sets of data points $($curve fitting is a subject to be

studied in ME$2500).$

a$)$ Using a function handle, define a MATLAB function that calculates the wind chill temperature

according to the following formula:

$=35\mathrm{.}74+0\mathrm{.}621535\mathrm{.}75$

$0\mathrm{.}16+0\mathrm{.}4275$

$0\mathrm{.}16$

where, the actual air temperature $$ and wind speed $$ are inputs to the function, and the wind

chill temperature $$ is the output. For this equation, the units for temperature and wind speed

are $\backslash$deg F and mph$,$ respectively.

b$)$ Use your function to calculate the wind chill temperature for $=25$ and $=15$ mph$.$

c$)$ Write a script file that does the following operations. Using the MATLAB built$-$in function plot

function, plot $($in red$)$ for $=45$ and $=0$ to $50$ mph$.$ On the same graph, plot $($in

blue$)$ for $=15$ and $=0$ to $50$ mph$.$ Be sure to label your graph properly, including the

legends, either by command lines or using the plot toolbox.

d$)$ Repeat part $($c$)$ by using the fplot function.
