The Kiepert hyperbola is a hyperbola and triangle conic that is related to the solution of Lemoine's problem and its generalization to isosceles triangles constructed on the ...

The Steiner circumellipse is the circumellipse that is the isotomic conjugate of the line at infinity and the isogonal conjugate of the Lemoine axis. It has circumconic ...

An anti-analytic function is a function f satisfying the condition (df)/(dz)=0. (1) Using the result ...

A function which has infinitely many derivatives at a point. If a function is not polygenic, it is monogenic.

If a function f has a pole at z_0, then the negative power part sum_(j=-k)^(-1)a_j(z-z_0)^j (1) of the Laurent series of f about z_0 sum_(j=-k)^inftya_j(z-z_0)^j (2) is ...

A function is termed regular iff it is analytic and single-valued throughout a region R.

The zeta Fuchsians are class of functions discovered by Poincaré which are related to the automorphic functions.

A locus is the set of all points (usually forming a curve or surface) satisfying some condition. For example, the locus of points in the plane equidistant from a given point ...

A variation of the method of false position for finding roots which fits the function in question with an exponential.

The tetranacci numbers are a generalization of the Fibonacci numbers defined by T_0=0, T_1=1, T_2=1, T_3=2, and the recurrence relation T_n=T_(n-1)+T_(n-2)+T_(n-3)+T_(n-4) ...
