Component form of a vector
If a vector’s representative in standard position has a terminal point (a,b) (or (a, b, c)) , then (a,b) (or (a, b, c)) is the component form of the vector, and a and b are the horizontal and vertical components of the vector (or a, b, and c are the x, y, and zcomponents of the vector, respectively)

Dot product
The number found when the corresponding components of two vectors are multiplied and then summed

Doubleangle identity
An identity involving a trigonometric function of 2u

Grapher or graphing utility
Graphing calculator or a computer with graphing software.

Hyperboloid of revolution
A surface generated by rotating a hyperbola about its transverse axis, p. 607.

Instantaneous rate of change
See Derivative at x = a.

Inverse of a matrix
The inverse of a square matrix A, if it exists, is a matrix B, such that AB = BA = I , where I is an identity matrix.

Invertible linear system
A system of n linear equations in n variables whose coefficient matrix has a nonzero determinant.

Lemniscate
A graph of a polar equation of the form r2 = a2 sin 2u or r 2 = a2 cos 2u.

Length of an arrow
See Magnitude of an arrow.

Mathematical induction
A process for proving that a statement is true for all natural numbers n by showing that it is true for n = 1 (the anchor) and that, if it is true for n = k, then it must be true for n = k + 1 (the inductive step)

Obtuse triangle
A triangle in which one angle is greater than 90°.

Period
See Periodic function.

Polar coordinate system
A coordinate system whose ordered pair is based on the directed distance from a central point (the pole) and the angle measured from a ray from the pole (the polar axis)

Product of matrices A and B
The matrix in which each entry is obtained by multiplying the entries of a row of A by the corresponding entries of a column of B and then adding

Projection of u onto v
The vector projv u = au # vƒvƒb2v
