Elliptic Integral of the Second Kind

Let the Modulus satisfy . (This may also be written in terms ofthe Parameter or Modular Angle .) The incomplete elliptic integralof the second kind is then defined as

(1)

A generalization replacing

with

gives

(2)

To place the elliptic integral of the second kind in a slightly different form, let

			(3)
			(4)

so the elliptic integral can also be written as


			(5)

The complete elliptic integral of the second kind, illustrated above as a function of the Parameter ,is defined by

			(6)
			(7)
			(8)
			(9)

where

is the Hypergeometric Function and

is a Jacobi Elliptic Function. The complete elliptic integral of the second kind satisfies the Legendre Relation

(10)

where

and

are complete Elliptic Integrals of the First and second kinds,and

and

are the complementary integrals. The Derivative is

(Whittaker and Watson 1990, p. 521). If

is a singular value (i.e.,

(12)

where

is the Elliptic Lambda Function), and

and the Elliptic Alpha Function

arealso known, then
