Abstract in different language: We find an explicit formula for the coefficients $\alpha_n$, $n \in \mathbb{N}$, of the generalized Maclaurin series for $\sin_p$ provided $p > 2$ is an integer. 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 \[ \alpha_n = \frac{\lim_{x \to 0+} \sin_p^{(np + 1)}(x)}{(np + 1)!}\,. \]
