Except for triangles, every simple polygon has at least two nonoverlapping ears.

The two-point form of a line in the Cartesian plane passing through the points (x_1,y_1) and (x_2,y_2) is given by y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1), or equivalently, ...

An error in a statistical test which occurs when a true hypothesis is rejected (a false negative in terms of the null hypothesis).

Let graph G have p points v_i and graph H have p points u_i, where p>=3. Then if for each i, the subgraphs G_i=G-v_i and H_i=H-u_i are isomorphic, then the graphs G and H are ...

The function defined by U(p)=(p#)^(p#), where p is a prime number and p# is a primorial. The values for p=2, 3, ..., are 4, 46656, ...

An umbilic point, also called simply an umbilic, is a point on a surface at which the curvature is the same in any direction.

The algebra structure of linear functionals on polynomials of a single variable (Roman 1984, pp. 2-3).

An operator T which maps some basic polynomial sequence p_n(x) into another basic polynomial sequence q_n(x).

In set theory, a unary operation on set A is a function A->A. More generally, a unary operation is a function with exactly one operand, such as the factorial, square root, or ...
