Key Calculus Terms and definitions covered in this textbook
• Anchor

See Mathematical induction.

• Complements or complementary angles

Two angles of positive measure whose sum is 90°

• Components of a vector

See Component form of a vector.

• Continuous function

A function that is continuous on its entire domain

• Cosine

The function y = cos x

• Definite integral

The definite integral of the function ƒ over [a,b] is Lbaƒ(x) dx = limn: q ani=1 ƒ(xi) ¢x provided the limit of the Riemann sums exists

• Elimination method

A method of solving a system of linear equations

• Inductive step

See Mathematical induction.

• Inequality

A statement that compares two quantities using an inequality symbol

• Inverse sine function

The function y = sin-1 x

• Octants

The eight regions of space determined by the coordinate planes.

• One-to-one rule of exponents

x = y if and only if bx = by.

• Partial fraction decomposition

See Partial fractions.

• Power rule of logarithms

logb Rc = c logb R, R 7 0.

• Pseudo-random numbers

Computer-generated numbers that can be used to approximate true randomness in scientific studies. Since they depend on iterative computer algorithms, they are not truly random

• Replication

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

• Solve by elimination or substitution

Methods for solving systems of linear equations.

• Terminal point

See Arrow.

• Trichotomy property

For real numbers a and b, exactly one of the following is true: a < b, a = b , or a > b.

• z-coordinate

The directed distance from the xy-plane to a point in space, or the third number in an ordered triple.
