Our method is based on an expression of the $n$-th derivative of $\sin_p$ in the form $\sum_{k = 0}^{2^{n - 2} - 1} a_{k,n} \sin_p^{p - 1}(x)\cos_p^{2 - p}(x)\,, \quad x\in \left(0, \frac{\pi_p}{2}\right),$ where $\cos_p$ stands for the first derivative of $\sin_p$. The formula allows us to compute the nonzero coefficients $\alpha_n = \frac{\lim_{x \to 0+} \sin_p^{(np + 1)}(x)}{(np + 1)!}\,.$ Rights: Plný text je přístupný v rámci univerzity přihlášeným uživatelům.© Texas State University, Department of Mathematics-CC-BY Appears in Collections: Články / Articles (KMA)OBD
