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::.
