Could you please tell me how to convert degrees to radians, and vice 
versa?

Sincerely,

It is really quite simple if you remember two things. Working in 
degrees, one revolution is 360 degrees.  When working in radians, 
there are two pi(2 times pi) radians in one revolution.  So it becomes 
evident that 

  360 degrees = 2 pi radians

so that  

  1 degree = 2 pi/360 radians = .0175 rad (approx)
or  
  1 radian = 360/(2 pi) = 57.3 degrees (approx)

To convert radians into degrees you should multiply by 180/pi.
To convert degrees into radians you should multiply by pi/180.

Hope that this helps.
