Key Calculus Terms and definitions covered in this textbook
• Direct variation

See Power function.

• Event

A subset of a sample space.

• First octant

The points (x, y, z) in space with x > 0 y > 0, and z > 0.

• Focal length of a parabola

The directed distance from the vertex to the focus.

• Initial point

See Arrow.

• Lower bound of f

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

• Mapping

A function viewed as a mapping of the elements of the domain onto the elements of the range

• 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)

• Midpoint (on a number line)

For the line segment with endpoints a and b, a + b2

• Natural logarithmic function

The inverse of the exponential function y = ex, denoted by y = ln x.

• Normal curve

The graph of ƒ(x) = e-x2/2

• Polynomial in x

An expression that can be written in the form an x n + an-1x n-1 + Á + a1x + a0, where n is a nonnegative integer, the coefficients are real numbers, and an ? 0. The degree of the polynomial is n, the leading coefficient is an, the leading term is anxn, and the constant term is a0. (The number 0 is the zero polynomial)

• Projectile motion

The movement of an object that is subject only to the force of gravity

• Range (in statistics)

The difference between the greatest and least values in a data set.

• Reciprocal of a real number

See Multiplicative inverse of a real number.

• Reduced row echelon form

A matrix in row echelon form with every column that has a leading 1 having 0’s in all other positions.

• Series

A finite or infinite sum of terms.

• Summation notation

The series a nk=1ak, where n is a natural number ( or ?) is in summation notation and is read "the sum of ak from k = 1 to n(or infinity).” k is the index of summation, and ak is the kth term of the series

• Vertical line test

A test for determining whether a graph is a function.

• Xmin

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