Create a javascript program:

• Write a function that performs a calculation. For example, here is a function that converts a length in inches into centimeters:

  function in2cm(inches) { var cm = inches * 2.54; return cm; } 

• Test your function. You can hardcode the input values for your function or you can use a prompt box to interactively enter the input values.
• Show the output from your function with a prompt box or using the document.writeln method
• Here are some examples of calculations:
  1. Convert radians to degrees, minutes, and seconds.
  2. Convert light years to parsecs.
  3. Compute the roots of a quadratic equation.
  4. Compute the wind chill, using the temperature and wind speed as inputs.
  5. Convert a course score to a course grade.
  6. For football fans: compute a passer rating using the inputs number of passing attempts, number of completions, passing yards, touchdown passes, interceptions. Find the formula on Wikipedia.
