The interior of a set is the union of all its open subsets. More informally, the interior of geometric structure is that portion of a region lying "inside" a specified ...

An irreducible fraction is a fraction p/q for which GCD(p,q)=1, i.e., p and q are relatively prime. For example, in the complex plane, (4+7i)/(2+i)=3+2i is reducible, while ...

The isogonal transform of a geometric object is the object obtained by collectively taking the isogonal conjugates of all its points.

Isomorphism is a very general concept that appears in several areas of mathematics. The word derives from the Greek iso, meaning "equal," and morphosis, meaning "to form" or ...

The isotomic transform of a geometric object is the object obtained by collectively taking the isotomic conjugates of all its points.

For 0<=x<=pi/2, 2/pix<=sinx<=x.

A quantity involving primitive cube roots of unity which can be used to solve the cubic equation.

(theta_3(z,t)theta_4(z,t))/(theta_4(2z,2t))=(theta_3(0,t)theta_4(0,t))/(theta_4(0,2t))=(theta_2(z,t)theta_1(z,t))/(theta_1(2z,2t)), where theta_i are Jacobi theta functions. ...

The fractal curve illustrated above, with base curve and motif illustrated below.

A mensuration formula is simply a formula for computing the length-related properties of an object (such as area, circumradius, etc., of a polygon) based on other known ...
