I need to know how to:

Create an HTML document which contains two text fields, a button, and a div. The first text field should be labeled Temperature, and the second should be labeled Wind Speed. The button should have the text Wind Chill written on it. Write two functions with these headers:

function doInputOutput() function windChill(tempF, speed) 

The first function (doInputOutput) must be called from the onclick attribute of the button and must do the following:

Get a temperature from the first text field

Get a wind speed from the second text field

Call the second function (windChill)

Store the value returned by windChill in a variable

Output the value returned by windChill to the div for the user to see

The second function (windChill) must

Take a temperature in Fahrenheit as a parameter

Take a wind speed in miles per hour as a parameter

Calculate the wind chill factor as a temperature in Fahrenheit

Return the wind chill factor in Fahrenheit

In other words, the second function (windChill) must not gather any input from a user and must not output anything for a user to see. Instead, it must calculate and return the result which makes this second function very reusable in other projects.

The formula for computing the wind chill factor is

f = 35.74 + 0.6215 t - 35.75 s^0.16 + 0.4275 t s^0.16

where f is the wind chill factor in Fahrenheit, t is the air temperature in Fahrenheit, and s is the wind speed in miles per hour at five feet above the ground.
