Hi Jamal,

For Sin(Ø) and Cos(Ø) you can use:
=SIN(RADIANS(C3)) and =COS(RADIANS(C3))
or:
=SIN(RADIANS(B3*24)) and =COS(RADIANS(B3*24))
in row 3 and copy down. This is more accurate than using your 3.14/180 conversion. For radians, you can use =RADIANS(C3) or =RADIANS(B3*24)

I'm not sure what you mean by:
In decimal terms, your angles add up to 540.0002778 degrees.
