wp34s Tn and Un
What are Tn and Un supposed to calculate? I know, it says "Chebyshev polynomials", but specifically?
For example, T1(x)=x according to most definitions I saw. When I do 1 <enter> 0.5 Tn I get 0.5, 1 <Enter> 0.8 Tn > 0.28.

RE: wp34s Tn and Un
This was a firmware bug. For n=1, the orthogonal polynomial code was returning the n=2 value.
That is, T_{1}(x) returned T_{2}(x). For n>1, the correct answer was returned. Fixed in the repository but it will have to wait for builds to be done. Pauli
