Algorithms for trig. on scientific calculators ?

[Commie]

Here is an example of how calculators calculate sine, using the Pade algorithm. To increase the accuracy further just involves using more terms.

This particular equation was generated using Derive 6 math package and is good between pi/2 to -pi/2. Using a condition statement the user/programmer can extend the dynamic range from pi to -pi.
