Key Calculus Terms and definitions covered in this textbook
• Arc length formula

The length of an arc in a circle of radius r intercepted by a central angle of u radians is s = r u.

• Argument of a complex number

The argument of a + bi is the direction angle of the vector {a,b}.

• Binomial coefficients

The numbers in Pascal’s triangle: nCr = anrb = n!r!1n - r2!

• Central angle

An angle whose vertex is the center of a circle

• Common logarithm

A logarithm with base 10.

• Distance (in Cartesian space)

The distance d(P, Q) between and P(x, y, z) and Q(x, y, z) or d(P, Q) ((x ) - x 2)2 + (y1 - y2)2 + (z 1 - z 2)2

• Equal matrices

Matrices that have the same order and equal corresponding elements.

• Event

A subset of a sample space.

• Focal length of a parabola

The directed distance from the vertex to the focus.

• Imaginary unit

The complex number.

• Line graph

A graph of data in which consecutive data points are connected by line segments

• Removable discontinuity at x = a

lim x:a- ƒ(x) = limx:a+ ƒ(x) but either the common limit is not equal ƒ(a) to ƒ(a) or is not defined

• Replication

The principle of experimental design that minimizes the effects of chance variation by repeating the experiment multiple times.

• Solve a triangle

To find one or more unknown sides or angles of a triangle

• Solve by substitution

Method for solving systems of linear equations.

• Standard form of a polynomial function

ƒ(x) = an x n + an-1x n-1 + Á + a1x + a0

• 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>

• Upper bound test for real zeros

A test for finding an upper bound for the real zeros of a polynomial.

• Vertical component

See Component form of a vector.

• Vertical line test

A test for determining whether a graph is a function.
