deg
Returns the degree of a polynomial expression.
With no variable argument, deg returns the total degree: the largest sum of powers in any term. With a variable, it returns the largest power of that variable while treating other variables as coefficients.
If the input cannot be converted to a polynomial, the operation remains symbolic.
Examples
These examples use Nerdamer Notation.
Return the total degree of a multivariable polynomial.
deg(x^2*y^3+x) // → 5
Return the degree with respect to x.
deg(x^2*y^3+x,x) // → 2
Return the degree with respect to y.
deg(x^2*y^3+x,y) // → 3
Interfaces
The same operation is available through the interfaces below.
Nerdamer Notation
Use this form inside input passed to nerdamer(...).
deg(arg1, [arg2])nerdamer.deg
Call the operation through the default nerdamer import.
nerdamer.deg(x: ExpressionInput | Polynomial): ExpressionParameters
| Name | Type | Description |
|---|---|---|
x | ExpressionInput | Polynomial | Expression-like input or polynomial to inspect. |
Returns
Expression — A numeric expression for a converted polynomial, otherwise an unevaluated symbolic `deg` call.
Direct JavaScript / TypeScript API
Import the operation directly from its package entry point.
import { deg } from 'nerdamer/algebra';deg(x: ExpressionInput | Polynomial): ExpressionParameters
| Name | Type | Description |
|---|---|---|
x | ExpressionInput | Polynomial | Expression-like input or polynomial to inspect. |
Returns
Expression — A numeric expression for a converted polynomial, otherwise an unevaluated symbolic `deg` call.
