Integer that remains unchanged when its digits are written in reverse order.

P (2)

A method for finding the volume of a solid of revolution. The volume equals the product of the area of the region being rotated times the distance traveled by the centroid of the region in one rotation.

P (1)

For a given point, called the focus, and a given line not through the focus, called the directrix, it is the locus of points such that the distance to the focus equals the distance to the directrix.

P (2)

The assumption that, given a point P and a line m not through P, there is exactly one line passing through P that is parallel to m.

P (1)

A polyhedron with six faces, all of which are parallelograms.

P (2)

A system of equations with more than one dependent variable; are often used to represent the position of a moving point.

P (2)

A derivative of a function that has more than one independent variable

P (3)

A differential equation that contains at least one partial derivative.

P (2)

The process of writing any proper rational expression as a sum of proper rational expressions.

P (4)

A finite sequence of the form a = x_{0} < x_{1} < x_{2} < ... < x_{n} = b.

P (5)

Rewriting a positive integer as the sum of smaller positive integers; the sum of any two adjacent elements in a row can be found between them on the next row; each row begins and ends with 1.

P (2)

A number n for which the sum of all the positive integer factors of n which are less than n add up to n.

P (2)

A function f for which there exists a number p such that f(x + p) = f(x) for all x.
