Struct SeriesMethods 

pub struct SeriesMethods;

Series expansion methods and utilities

Implementations

impl SeriesMethods

pub fn factorial(n: u32) -> Expression

Compute factorial

pub fn binomial_coefficient(n: u32, k: u32) -> Expression

Compute binomial coefficient

pub fn known_series( function_name: &str, variable: &Symbol, point: &Expression, order: u32, ) -> Option<Expression>

Get known series expansion for common functions

pub fn general_taylor_series( expr: &Expression, variable: &Symbol, point: &Expression, order: u32, ) -> Expression

Compute general Taylor series using derivatives

Taylor series: f(x) = Σ [f^(n)(a) / n!] * (x-a)^n

For noncommutative expressions, order is preserved:

• Derivative f^(n)(a) comes first
• Power (x-a)^n comes second
• Division by n! comes last

pub fn evaluate_at_point( expr: &Expression, variable: &Symbol, point: &Expression, ) -> Expression

Evaluate expression at a specific point
