Key Calculus Terms and definitions covered in this textbook
• Angle between vectors

The angle formed by two nonzero vectors sharing a common initial point

• Annual percentage yield (APY)

The rate that would give the same return if interest were computed just once a year

• Complements or complementary angles

Two angles of positive measure whose sum is 90°

• Conjugate axis of a hyperbola

The line segment of length 2b that is perpendicular to the focal axis and has the center of the hyperbola as its midpoint

• Difference identity

An identity involving a trigonometric function of u - v

• 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

• Endpoint of an interval

A real number that represents one “end” of an interval.

• Frequency (in statistics)

The number of individuals or observations with a certain characteristic.

• Half-plane

The graph of the linear inequality y ? ax + b, y > ax + b y ? ax + b, or y < ax + b.

• Inverse reflection principle

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

• Leibniz notation

The notation dy/dx for the derivative of ƒ.

• nth root

See Principal nth root

• Partial fractions

The process of expanding a fraction into a sum of fractions. The sum is called the partial fraction decomposition of the original fraction.

• Polynomial function

A function in which ƒ(x)is a polynomial in x, p. 158.

• Repeated zeros

Zeros of multiplicity ? 2 (see Multiplicity).

• Sinusoid

A function that can be written in the form f(x) = a sin (b (x - h)) + k or f(x) = a cos (b(x - h)) + k. The number a is the amplitude, and the number h is the phase shift.

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

• Terms of a sequence

The range elements of a sequence.

• Venn diagram

A visualization of the relationships among events within a sample space.

• x-axis

Usually the horizontal coordinate line in a Cartesian coordinate system with positive direction to the right,.
