integral.polynomial {polynom} | R Documentation

## Integrate a Polynomial

### Description

Find the integral of a univariate polynomial.

### Usage

    ## S3 method for class 'polynomial'
    integral(expr, limits = NULL, ...)

### Arguments

`expr` | an object of class `"polynomial"`.
`limits` | numeric vector of length 2 giving the integration limits.
`...` | further arguments to be passed to or from methods.

### Value

If `limits` is not given, the integral of `p` from 0 to ‘x’'. Otherwise, the integral with the given integration limits.

### See Also

`deriv.polynomial`

### Examples

    p <- poly.calc(1:5)
    p
    ## -120 + 274*x - 225*x^2 + 85*x^3 - 15*x^4 + x^5
    deriv(p)
    ## 274 - 450*x + 255*x^2 - 60*x^3 + 5*x^4
    integral(deriv(p)) - 120
    ## -120 + 274*x - 225*x^2 + 85*x^3 - 15*x^4 + x^5
