I am looking for coefficients (floating point) for 5th degree chebyshev sine/cosine function. Could any body help me with this. Purpose is to implement custom trig function in a microcontroller

I was looking for coeff in the range -pi to +pi, which is not listed in this page

Also look at a CORDIC implementation. It is probably better than polynomial implementations in small microcontrollers, especially if multiplication (with the required precision) can't be done in hardware.
