README

  This is the readme file for HW9:
  The program is used to compute sin(x) for a given list of input floats (redirectable from a file) all of which are between 0 and 1.
  two procedures in seperate input files:  
     corsin.h:This One computes the sine using the CORDIC algorithm.
     msin.h:  This one computes the sine using a truncated Maclaurin polynomial of order 7 in Horner form. 
  After comparing the result, I can see the second method is more precise than the first one.
Example to Use:
