Key Calculus Terms and definitions covered in this textbook
• Angular speed

Speed of rotation, typically measured in radians or revolutions per unit time

• Axis of symmetry

See Line of symmetry.

• Coefficient matrix

A matrix whose elements are the coefficients in a system of linear equations

• Coefficient of determination

The number r2 or R2 that measures how well a regression curve fits the data

• Fibonacci numbers

The terms of the Fibonacci sequence.

• Infinite discontinuity at x = a

limx:a + x a ƒ(x) = q6 or limx:a - ƒ(x) = q.

• Interval

Connected subset of the real number line with at least two points, p. 4.

• Inverse cosine function

The function y = cos-1 x

• Inverse tangent function

The function y = tan-1 x

• Line of symmetry

A line over which a graph is the mirror image of itself

• nth power of a

The number with n factors of a , where n is the exponent and a is the base.

• nth root

See Principal nth root

• Orthogonal vectors

Two vectors u and v with u x v = 0.

• Parallelogram representation of vector addition

Geometric representation of vector addition using the parallelogram determined by the position vectors.

• 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 functions

(ƒg)(x) = ƒ(x)g(x)

• Singular matrix

A square matrix with zero determinant

• Terms of a sequence

The range elements of a sequence.

• Vector equation for a line in space

The line through P0(x 0, y0, z0) in the direction of the nonzero vector V = <a, b, c> has vector equation r = r0 + tv , where r = <x,y,z>.

• Window dimensions

The restrictions on x and y that specify a viewing window. See Viewing window.
