Function help
Author
I haven''t had Trig in like two years and I''ve forgotten how to create functions from two patterns (X and Y). Can someone help me out? The two patterns are:
X: 0 1 2 3 4 5 6 7
Y: 2 1 0 7 6 5 4 3
I need a function to determine the Y when I only have X.

There''s no obvious polynomial or trigonomic pattern that fits. It does appear to be a shifted sawtooth wave though:
7 \ \6 \ \5 \ \4 \ \3 \ \2 \ \ \1 \ \ \0 \ \ \X: 01234567__________ Y = 7 - (X + 5) mod 8; // (or whatever the modulus operator is...)
With that many numbers in the sample, you could fit a 7th order polynomial, but that''s probably not what you''re looking for.
