Key Calculus Terms and definitions covered in this textbook
• Arithmetic sequence

A sequence {an} in which an = an-1 + d for every integer n ? 2 . The number d is the common difference.

• Constant of variation

See Power function.

• Divergence

A sequence or series diverges if it does not converge

• Equal matrices

Matrices that have the same order and equal corresponding elements.

• Gaussian elimination

A method of solving a system of n linear equations in n unknowns.

• Logarithmic form

An equation written with logarithms instead of exponents

• Lower bound of f

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

• Magnitude of a vector

The magnitude of <a, b> is 2a2 + b2. The magnitude of <a, b, c> is 2a2 + b2 + c2

• Mathematical model

A mathematical structure that approximates phenomena for the purpose of studying or predicting their behavior

• Minor axis

The perpendicular bisector of the major axis of an ellipse with endpoints on the ellipse.

• Odd-even identity

For a basic trigonometric function f, an identity relating f(x) to f(-x).

• Principle of mathematical induction

A principle related to mathematical induction.

• Product of functions

(ƒg)(x) = ƒ(x)g(x)

• Right triangle

A triangle with a 90° angle.

• Solve graphically

Use a graphical method, including use of a hand sketch or use of a grapher. When appropriate, the approximate solution should be confirmed algebraically

• Spiral of Archimedes

The graph of the polar curve.

• Standard form of a complex number

a + bi, where a and b are real numbers

• Statistic

A number that measures a quantitative variable for a sample from a population.

• Statute mile

5280 feet.

• Vector equation for a line in space

The line through P0(x 0, y0, z0) in the direction of the nonzero vector V = <a, b, c> has vector equation r = r0 + tv , where r = <x,y,z>.
