`simplify`

Rewrites an expression into a simpler equivalent form using Nerdamer's symbolic simplification rules.

Simplification includes algebraic cancellation, polynomial and rational reduction, selected identities, factorial cancellation, radical simplification, and simplification inside function arguments.

The result remains symbolic. Nerdamer only applies transformations it can justify from the expression and any available assumptions.

Examples

These examples use Nerdamer Notation.

Cancel a common polynomial factor.

simplify((x^2+2*x+1)/(x+1))
// → 1+x

Apply a trigonometric identity.

simplify(sin(x)^2+cos(x)^2)
// → 1

Cancel adjacent factorials symbolically.

simplify(n!/(n+1)!)
// → (1+n)^-1

Nerdamer Notation

Use this form inside input passed to nerdamer(...).

simplify(arg1)

`nerdamer.simplify`

Call the operation through the default nerdamer import.

nerdamer.simplify(x: string | Expression, modifiers: { … }): Expression

Parameters

Name	Type	Description
`x`	`string \| Expression`	Expression or parser text to simplify.
`modifiers`	`{ … }`	Internal recursion markers used to detect an unchanged image.

Returns

Expression — The simplified expression, which may retain forms unsupported by the finite strategy set.
