Key Calculus Terms and definitions covered in this textbook
• artesian coordinate system

An association between the points in a plane and ordered pairs of real numbers; or an association between the points in three-dimensional space and ordered triples of real numbers

• Binomial probability

In an experiment with two possible outcomes, the probability of one outcome occurring k times in n independent trials is P1E2 = n!k!1n - k2!pk11 - p) n-k where p is the probability of the outcome occurring once

• Cardioid

A limaçon whose polar equation is r = a ± a sin ?, or r = a ± a cos ?, where a > 0.

• Categorical variable

In statistics, a nonnumerical variable such as gender or hair color. Numerical variables like zip codes, in which the numbers have no quantitative significance, are also considered to be categorical.

• Distance (in a coordinate plane)

The distance d(P, Q) between P(x, y) and Q(x, y) d(P, Q) = 2(x 1 - x 2)2 + (y1 - y2)2

• Dot product

The number found when the corresponding components of two vectors are multiplied and then summed

• Elements of a matrix

See Matrix element.

• Equation

A statement of equality between two expressions.

• Hypotenuse

Side opposite the right angle in a right triangle.

• Imaginary axis

See Complex plane.

• Logarithm

An expression of the form logb x (see Logarithmic function)

• Logarithmic regression

See Natural logarithmic regression

• nth power of a

The number with n factors of a , where n is the exponent and a is the base.

• Quotient rule of logarithms

logb a R S b = logb R - logb S, R > 0, S > 0

• Reference angle

See Reference triangle

• Sine

The function y = sin x.

• Slant asymptote

An end behavior asymptote that is a slant line

• Solution of an equation or inequality

A value of the variable (or values of the variables) for which the equation or inequality is true
