series(Function, Identifier, Real)

series(Function, Identifier, Real, Natural)

Given a function $f\left(x_1,...,x_n\right)$, an identifier $x_i$ and a real $x_0$, expands function $f$ with respect to variable $x_i$ around the point $x_0$.

Given a function $f\left(x_1,...,x_n\right)$, an identifier $x_i$, a real $x_0$ and a natural $n$, expands function $f$ with respect to variable $x_i$ around the point $x_0$ up to order $n$.
