Key Calculus Terms and definitions covered in this textbook
• Angle

Union of two rays with a common endpoint (the vertex). The beginning ray (the initial side) can be rotated about its endpoint to obtain the final position (the terminal side)

• Aphelion

The farthest point from the Sun in a planet’s orbit

• Arcsecant function

See Inverse secant function.

• Compounded annually

See Compounded k times per year.

• Cotangent

The function y = cot x

• Derivative of ƒ

The function defined by ƒ'(x) = limh:0ƒ(x + h) - ƒ(x)h for all of x where the limit exists

• Exponential decay function

Decay modeled by ƒ(x) = a ? bx, a > 0 with 0 < b < 1.

• Law of sines

sin A a = sin B b = sin C c

• Minute

Angle measure equal to 1/60 of a degree.

• Mode of a data set

The category or number that occurs most frequently in the set.

• Natural logarithm

A logarithm with base e.

• Objective function

See Linear programming problem.

• Period

See Periodic function.

• Probability distribution

The collection of probabilities of outcomes in a sample space assigned by a probability function.

• Random numbers

Numbers that can be used by researchers to simulate randomness in scientific studies (they are usually obtained from lengthy tables of decimal digits that have been generated by verifiably random natural phenomena).

• Rational numbers

Numbers that can be written as a/b, where a and b are integers, and b ? 0.

• Right triangle

A triangle with a 90° angle.

• Scatter plot

A plot of all the ordered pairs of a two-variable data set on a coordinate plane.

• Sum of functions

(ƒ + g)(x) = ƒ(x) + g(x)

• Time plot

A line graph in which time is measured on the horizontal axis.
