numpy.polyint(p, m) : Evaluates the anti – derivative of a polynomial with the specified order.
m antiderivative ‘P’ of polynomial ‘p’ satisfies
p : [array_like or poly1D] polynomial coefficients are given in decreasing order of powers. If the second parameter (root) is set to True then array values are the roots of the polynomial equation. For example, poly1d(3, 2, 6) = 3x2 + 2x + 6
m : [int, optional] Order of anti-derivative. Default is 1.
Return: Anti-Derivative of the polynomial.
P1 : 1 x + 2 p2 : 3 2 4 x + 9 x + 5 x + 4 p1 at x = 2 : 4 p2 at x = 2 : 82 Using polyint p1 anti-derivative of order = 1 : 2 0.5 x + 2 x p2 anti-derivative of order = 1 : 4 3 2 1 x + 3 x + 2.5 x + 4 x
