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

See Magnitude of a vector.

P(A or B) = P(A) + P(B) - P(A and B). If A and B are mutually exclusive events, then P(A or B) = P(A) + P(B)

• Arrow

The notation PQ denoting the directed line segment with initial point P and terminal point Q.

• First octant

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

• Inverse reflection principle

If the graph of a relation is reflected across the line y = x , the graph of the inverse relation results.

• kth term of a sequence

The kth expression in the sequence

• Normal curve

The graph of ƒ(x) = e-x2/2

• Obtuse triangle

A triangle in which one angle is greater than 90°.

• Permutation

An arrangement of elements of a set, in which order is important.

• Product of functions

(ƒg)(x) = ƒ(x)g(x)

The measure of an angle in radians, or, for a central angle, the ratio of the length of the intercepted arc tothe radius of the circle.

• Reference angle

See Reference triangle

• Resistant measure

A statistical measure that does not change much in response to outliers.

• Resolving a vector

Finding the horizontal and vertical components of a vector.

• Scatter plot

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

• Symmetric matrix

A matrix A = [aij] with the property aij = aji for all i and j

• System

A set of equations or inequalities.

• Whole numbers

The numbers 0, 1, 2, 3, ... .

• Zero matrix

A matrix consisting entirely of zeros.

• Zero vector

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