Problem B11

• Problem B11 calculates the values of cosine for
  angles between 0 and 90 degrees.
• You are provided with a partial program that has
  a main() function. You are to write
• the function mycos(x, terms)
• the function myfactorial(n)
• Prototypes for mycos() and myfactorial() are
  provided
• The main program will compare the calculations of
  your mycos() function with the cos() function
  from the math.h library.
