Key Calculus Terms and definitions covered in this textbook
• Absolute value of a real number

Denoted by |a|, represents the number a or the positive number -a if a < 0.

• Cofunction identity

An identity that relates the sine, secant, or tangent to the cosine, cosecant, or cotangent, respectively

• Component form of a vector

If a vector’s representative in standard position has a terminal point (a,b) (or (a, b, c)) , then (a,b) (or (a, b, c)) is the component form of the vector, and a and b are the horizontal and vertical components of the vector (or a, b, and c are the x-, y-, and z-components of the vector, respectively)

• Conic section (or conic)

A curve obtained by intersecting a double-napped right circular cone with a plane

• Grapher or graphing utility

Graphing calculator or a computer with graphing software.

• Independent events

Events A and B such that P(A and B) = P(A)P(B)

• Infinite discontinuity at x = a

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

• Initial value of a function

ƒ 0.

• Lower bound of f

Any number b for which b < ƒ(x) for all x in the domain of ƒ

• Main diagonal

The diagonal from the top left to the bottom right of a square matrix

• Mathematical induction

A process for proving that a statement is true for all natural numbers n by showing that it is true for n = 1 (the anchor) and that, if it is true for n = k, then it must be true for n = k + 1 (the inductive step)

• Matrix element

Any of the real numbers in a matrix

• Mode of a data set

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

• Opposite

See Additive inverse of a real number and Additive inverse of a complex number.

• Permutations of n objects taken r at a time

There are nPr = n!1n - r2! such permutations

• Rational zeros

Zeros of a function that are rational numbers.

• Stretch of factor c

A transformation of a graph obtained by multiplying all the x-coordinates (horizontal stretch) by the constant 1/c, or all of the y-coordinates (vertical stretch) of the points by a constant c, c, > 1.

• Variable (in statistics)

A characteristic of individuals that is being identified or measured.

• Xmin

The x-value of the left side of the viewing window,.

• Zero vector

The vector <0,0> or <0,0,0>.
