Struct ChainRule 

pub struct ChainRule;

Chain rule implementation for function derivatives

Implementations

impl ChainRule

pub fn handle_function( name: &str, args: &[Expression], variable: Symbol, ) -> Expression

Handle derivative of function expressions using chain rule

Examples

use mathhook_core::simplify::Simplify;
use mathhook_core::{Expression, symbol};
use mathhook_core::calculus::derivatives::Derivative;

let x = symbol!(x);
let expr = Expression::function("sin", vec![Expression::symbol(x.clone())]);
let result = expr.derivative(x.clone());

pub fn apply( function_name: &str, arg: &Expression, variable: Symbol, ) -> Expression

Apply chain rule for function derivatives

Examples

use mathhook_core::{Expression, symbol};
use mathhook_core::calculus::derivatives::ChainRule;

let x = symbol!(x);
let arg = Expression::pow(Expression::symbol(x.clone()), Expression::integer(2));
let result = ChainRule::apply("sin", &arg, x.clone());
