Key Calculus Terms and definitions covered in this textbook
• Cotangent

The function y = cot x

• End behavior asymptote of a rational function

A polynomial that the function approaches as.

• equation of an ellipse

(x - h2) a2 + (y - k)2 b2 = 1 or (y - k)2 a2 + (x - h)2 b2 = 1

• Frequency distribution

See Frequency table.

• Graphical model

A visible representation of a numerical or algebraic model.

• Heron’s formula

The area of ¢ABC with semiperimeter s is given by 2s1s - a21s - b21s - c2.

• Imaginary unit

The complex number.

• Inverse composition rule

The composition of a one-toone function with its inverse results in the identity function.

• Inverse cosine function

The function y = cos-1 x

• Irrational numbers

Real numbers that are not rational, p. 2.

• Numerical model

A model determined by analyzing numbers or data in order to gain insight into a phenomenon, p. 64.

• Positive angle

Angle generated by a counterclockwise rotation.

• Quartic regression

A procedure for fitting a quartic function to a set of data.

• Sample survey

A process for gathering data from a subset of a population, usually through direct questioning.

• Sequence

See Finite sequence, Infinite sequence.

• Sinusoid

A function that can be written in the form f(x) = a sin (b (x - h)) + k or f(x) = a cos (b(x - h)) + k. The number a is the amplitude, and the number h is the phase shift.

• Slant asymptote

An end behavior asymptote that is a slant line

• Solve a system

To find all solutions of a system.

• Standard unit vectors

In the plane i = <1, 0> and j = <0,1>; in space i = <1,0,0>, j = <0,1,0> k = <0,0,1>

• Vertical translation

A shift of a graph up or down.
