16.3 Functions and Variables for Elliptic Integrals
===================================================
-- Function: elliptic_f (<phi>, <m>)
The incomplete elliptic integral of the first kind, defined as
integrate(1/sqrt(1 - m*sin(x)^2), x, 0, phi)
See also Note: elliptic_e and Note: elliptic_kc.
-- Function: elliptic_e (<phi>, <m>)
The incomplete elliptic integral of the second kind, defined as
elliptic_e(phi, m) = integrate(sqrt(1 - m*sin(x)^2), x, 0, phi)
See also Note: elliptic_f and Note: elliptic_ec.
-- Function: elliptic_eu (<u>, <m>)
The incomplete elliptic integral of the second kind, defined as
integrate(dn(v,m)^2,v,0,u) = integrate(sqrt(1-m*t^2)/sqrt(1-t^2),
t, 0, tau)
where tau = sn(u,m).
This is related to elliptic_e by
elliptic_eu(u, m) = elliptic_e(asin(sn(u,m)),m)
See also Note: elliptic_e.
-- Function: elliptic_pi (<n>, <phi>, <m>)
The incomplete elliptic integral of the third kind, defined as
integrate(1/(1-n*sin(x)^2)/sqrt(1 - m*sin(x)^2), x, 0, phi)
-- Function: elliptic_kc (<m>)
The complete elliptic integral of the first kind, defined as
integrate(1/sqrt(1 - m*sin(x)^2), x, 0, %pi/2)
For certain values of m, the value of the integral is known in
terms of Gamma functions. Use 'makegamma' to evaluate them.
-- Function: elliptic_ec (<m>)
The complete elliptic integral of the second kind, defined as
integrate(sqrt(1 - m*sin(x)^2), x, 0, %pi/2)
For certain values of m, the value of the integral is known in
terms of Gamma functions. Use 'makegamma' to evaluate them.
