methods¶

degree -> () ¶

Polynomial:degree(

): number

returns the degree of the polynomial.

cutdeg -> () ¶

Polynomial:cutdeg(
    degree : number
): Polynomial

returns a copy of the polynomial thats trimmed to the degree degree.

copy -> () ¶

Polynomial:copy(

): Polynomial

returns a copy of the polynomial.

deriv -> () ¶

Polynomial:deriv(

): Polynomial

returns the derivative of the polynomial.

integ -> () ¶

Polynomial:integ(

): Polynomial
