Hello uug1,
In order to do this, you must use the taylor series..
Go to the bottom of this link... IT gives a LOT of info.

Alternatively, look at the PROTON+ compiler.
This does true floating point calculations including trigonometry.

I tried with Taylor series but no good.
For angles less than 45 degrees, the code seem to work ok, but for larger angles the deviation is high.
I have decided to use interpolation with select.
Appreciate the help I got from this place.
