Key Calculus Terms and definitions covered in this textbook
• Ambiguous case

The case in which two sides and a nonincluded angle can determine two different triangles

• Direct variation

See Power function.

• Empty set

A set with no elements

• Event

A subset of a sample space.

• Five-number summary

The minimum, first quartile, median, third quartile, and maximum of a data set.

• Hypotenuse

Side opposite the right angle in a right triangle.

• Intercept

Point where a curve crosses the x-, y-, or z-axis in a graph.

• Linear function

A function that can be written in the form ƒ(x) = mx + b, where and b are real numbers

• Periodic function

A function ƒ for which there is a positive number c such that for every value t in the domain of ƒ. The smallest such number c is the period of the function.

• Product of a scalar and a vector

The product of scalar k and vector u = 8u1, u29 1or u = 8u1, u2, u392 is k.u = 8ku1, ku291or k # u = 8ku1, ku2, ku392,

• Quartile

The first quartile is the median of the lower half of a set of data, the second quartile is the median, and the third quartile is the median of the upper half of the data.

• Rational zeros theorem

A procedure for finding the possible rational zeros of a polynomial.

• Reciprocal identity

An identity that equates a trigonometric function with the reciprocal of another trigonometricfunction.

• Scientific notation

• Second

Angle measure equal to 1/60 of a minute.

• Sine

The function y = sin x.

A graph in which (-x, y) is on the graph whenever (x, y) is; or a graph in which (-r, -?) or (r, ?, -?) is on the graph whenever (r, ?) is

• Tangent

The function y = tan x

• Unit vector

Vector of length 1.

• Zero factor property

If ab = 0 , then either a = 0 or b = 0.
