EllipticPi
can be applied to power series:
Applications
(4)
Carry out an elliptic integral:
Definition of the solid angle subtended by a disk (for instance a detector, a road sign) at the origin in the
,
-plane from a point
:
Closed form result for the solid angle:
Numerical comparison:
Plot the solid angle as a function of horizontal distance and height:
This calculates the classical action for a relativistic 3D oscillator:
The action can be expressed using
EllipticPi
(for brevity, occurring roots are abbreviated):
A conformal map:
Visualize the image of lines of constant real and imaginary parts:
Properties & Relations
(4)
Expand special cases using assumptions:
This shows the branch cuts of the
EllipticPi
function:
Numerically find a root of a transcendental equation:
Integrals:
Possible Issues
(3)
Limits at branch cuts can be wrong:
The defining integral converges only under additional conditions:
Different argument conventions exist that result in modified results:
