# ExpressionToUnivariatePowerSeries(R, FE)ΒΆ

This package provides functions to convert functional expressions to power series.

laurent: (FE, Equation FE) -> Any

`laurent(f, x = a)` expands the expression `f` as a Laurent series in powers of `(x - a)`.

laurent: (FE, Equation FE, Integer) -> Any

`laurent(f, x = a, n)` expands the expression `f` as a Laurent series in powers of `(x - a)`; terms will be computed up to order at least `n`.

laurent: (FE, Integer) -> Any

`laurent(f, n)` returns a Laurent expansion of the expression `f`. Note: `f` should have only one variable; the series will be expanded in powers of that variable and terms will be computed up to order at least `n`.

laurent: FE -> Any

`laurent(f)` returns a Laurent expansion of the expression `f`. Note: `f` should have only one variable; the series will be expanded in powers of that variable.

laurent: Symbol -> Any

`laurent(x)` returns `x` viewed as a Laurent series.

puiseux: (FE, Equation FE) -> Any

`puiseux(f, x = a)` expands the expression `f` as a Puiseux series in powers of `(x - a)`.

puiseux: (FE, Equation FE, Fraction Integer) -> Any

`puiseux(f, x = a, n)` expands the expression `f` as a Puiseux series in powers of `(x - a)`; terms will be computed up to order at least `n`.

puiseux: (FE, Fraction Integer) -> Any

`puiseux(f, n)` returns a Puiseux expansion of the expression `f`. Note: `f` should have only one variable; the series will be expanded in powers of that variable and terms will be computed up to order at least `n`.

puiseux: FE -> Any

`puiseux(f)` returns a Puiseux expansion of the expression `f`. Note: `f` should have only one variable; the series will be expanded in powers of that variable.

puiseux: Symbol -> Any

`puiseux(x)` returns `x` viewed as a Puiseux series.

series: (FE, Equation FE) -> Any

`series(f, x = a)` expands the expression `f` as a series in powers of (`x` - a).

series: (FE, Equation FE, Fraction Integer) -> Any

`series(f, x = a, n)` expands the expression `f` as a series in powers of (`x` - a); terms will be computed up to order at least `n`.

series: (FE, Fraction Integer) -> Any

`series(f, n)` returns a series expansion of the expression `f`. Note: `f` should have only one variable; the series will be expanded in powers of that variable and terms will be computed up to order at least `n`.

series: FE -> Any

`series(f)` returns a series expansion of the expression `f`. Note: `f` should have only one variable; the series will be expanded in powers of that variable.

series: Symbol -> Any

`series(x)` returns `x` viewed as a series.

taylor: (FE, Equation FE) -> Any

`taylor(f, x = a)` expands the expression `f` as a Taylor series in powers of `(x - a)`.

taylor: (FE, Equation FE, NonNegativeInteger) -> Any

`taylor(f, x = a)` expands the expression `f` as a Taylor series in powers of `(x - a)`; terms will be computed up to order at least `n`.

taylor: (FE, NonNegativeInteger) -> Any

`taylor(f, n)` returns a Taylor expansion of the expression `f`. Note: `f` should have only one variable; the series will be expanded in powers of that variable and terms will be computed up to order at least `n`.

taylor: FE -> Any

`taylor(f)` returns a Taylor expansion of the expression `f`. Note: `f` should have only one variable; the series will be expanded in powers of that variable.
