daha genel yazmak istersek $f : \mathbb{R}^n \to \mathbb{R}^n$ in $x+h$ daki Taylor acilimi
$f(x+h) = f(x) + \sum_{i=1}^{n} \dfrac{\partial f}{ \partial x_i}h_i + \frac{1}{2!} \sum_{i,j=1}^{n} \dfrac{\partial f}{ \partial x_i \partial x_j}(x)h_ih_j + \frac{1}{3!} \sum_{i,j,k=1}^{n} \dfrac{\partial f}{ \partial x_i \partial x_j \partial x_k}(x)h_ih_j h_k + \frac{1}{4!} \sum_{i,j,k,l=1}^{n} \dfrac{\partial f}{ \partial x_i \partial x_j \partial x_k \partial x_l}(x)h_ih_j h_kh_l + \cdots$
