Key Calculus Terms and definitions covered in this textbook
• Augmented matrix

A matrix that represents a system of equations.

• Circle graph

A circular graphical display of categorical data

• Directed distance

See Polar coordinates.

• Elements of a matrix

See Matrix element.

• End behavior asymptote of a rational function

A polynomial that the function approaches as.

• Expanded form

The right side of u(v + w) = uv + uw.

• Exponential function

A function of the form ƒ(x) = a ? bx,where ?0, b > 0 b ?1

• Higher-degree polynomial function

A polynomial function whose degree is ? 3

• Horizontal translation

A shift of a graph to the left or right.

• Inductive step

See Mathematical induction.

• Line of travel

The path along which an object travels

• Linear regression

A procedure for finding the straight line that is the best fit for the data

• Logarithmic regression

See Natural logarithmic regression

• Numerical derivative of ƒ at a

NDER f(a) = ƒ1a + 0.0012 - ƒ1a - 0.00120.002

• Observational study

A process for gathering data from a subset of a population through current or past observations. This differs from an experiment in that no treatment is imposed.

• Principal nth root

If bn = a, then b is an nth root of a. If bn = a and a and b have the same sign, b is the principal nth root of a (see Radical), p. 508.

• Reference triangle

For an angle ? in standard position, a reference triangle is a triangle formed by the terminal side of angle ?, the x-axis, and a perpendicular dropped from a point on the terminal side to the x-axis. The angle in a reference triangle at the origin is the reference angle

• Rose curve

A graph of a polar equation or r = a cos nu.

• Singular matrix

A square matrix with zero determinant
