integral.polynomial {polynom} | R Documentation |
Find the integral of a univariate polynomial.
integral(p, limits = NULL, ...)
p |
Object of class polynomial. |
limits |
numeric vector of length 2 giving the integration limits. |
If limits
is not given, the integral of p
from 0 to
`x'. Otherwise, the integral with the given integration limits.
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
