Hi,
I need little help about math for calculating Mean kinetic temperature.
I have 10-60 samples on same time interval.
First I was thinking that I maybe put this equation in exel or matlab, and then try to get polynomial, but with 60 variables, I think that is too much.

Second attempt is to implement logarithm and exponential in code by developing it to power series. But as far as I can see now problem is using only integers.

Accuracy about +/-0.5 should be acceptable. Does someone have some clever way to solve this?

p.s.
I'm using PIC18, so I can use LONG variables.
Thanks
