There is a non recursive formula for T(x,k)?
#2
An explicit formula, probably has  \( \\[15pt]

{x^k} \) as factor, because it looks like the Taylor series of  \( \\[15pt]

{^xb} \), which is higly probable to have  \( \\[15pt]

{ln(b)^k} \) as factor on the k derivative

Since the Taylor series is

\( ^xb=\sum_{k=0}^{\infty} \frac {1}{k!}*\frac{d^k (^xb)}{dx^k}|_0 *x^{k} \)


T(x,k) has to be


\( T(x,k)=\frac{d^k (^xb)}{dx^k}|_0 *\frac{x^{k}}{ln(b)^k} \)
I have the result, but I do not yet know how to get it.
