Key Calculus Terms and definitions covered in this textbook
• Additive identity for the complex numbers

0 + 0i is the complex number zero

• Angle

Union of two rays with a common endpoint (the vertex). The beginning ray (the initial side) can be rotated about its endpoint to obtain the final position (the terminal side)

• Annual percentage rate (APR)

The annual interest rate

• Arccosecant function

See Inverse cosecant function.

• Circle

A set of points in a plane equally distant from a fixed point called the center

• 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

• Continuous at x = a

lim x:a x a ƒ(x) = ƒ(a)

• Continuous function

A function that is continuous on its entire domain

• Difference of complex numbers

(a + bi) - (c + di) = (a - c) + (b - d)i

• Equation

A statement of equality between two expressions.

• Event

A subset of a sample space.

• Extracting square roots

A method for solving equations in the form x 2 = k.

• Frequency table (in statistics)

A table showing frequencies.

• Head minus tail (HMT) rule

An arrow with initial point (x1, y1 ) and terminal point (x2, y2) represents the vector <8x 2 - x 1, y2 - y19>

• Identity properties

a + 0 = a, a ? 1 = a

• Measure of center

A measure of the typical, middle, or average value for a data set

• 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)

• Semimajor axis

The distance from the center to a vertex of an ellipse.

• Standard deviation

A measure of how a data set is spread

• Unit vector in the direction of a vector

A unit vector that has the same direction as the given vector.
