Key Calculus Terms and definitions covered in this textbook
• Descriptive statistics

The gathering and processing of numerical information

• Difference of two vectors

<u1, u2> - <v1, v2> = <u1 - v1, u2 - v2> or <u1, u2, u3> - <v1, v2, v3> = <u1 - v1, u2 - v2, u3 - v3>

• Dot product

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

• Expanded form

The right side of u(v + w) = uv + uw.

• Exponential form

An equation written with exponents instead of logarithms.

• Graph of an equation in x and y

The set of all points in the coordinate plane corresponding to the pairs x, y that are solutions of the equation.

• Independent events

Events A and B such that P(A and B) = P(A)P(B)

• Logistic regression

A procedure for fitting a logistic curve to a set of data

• Mapping

A function viewed as a mapping of the elements of the domain onto the elements of the range

• Mode of a data set

The category or number that occurs most frequently in the set.

• Polynomial function

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

• Right angle

A 90° angle.

• Sample survey

A process for gathering data from a subset of a population, usually through direct questioning.

• Solution of an equation or inequality

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

• Solve a system

To find all solutions of a system.

• Standard form of a complex number

a + bi, where a and b are real numbers

• Synthetic division

A procedure used to divide a polynomial by a linear factor, x - a

• Weighted mean

A mean calculated in such a way that some elements of the data set have higher weights (that is, are counted more strongly in determining the mean) than others.

• Whole numbers

The numbers 0, 1, 2, 3, ... .

• Ymax

The y-value of the top of the viewing window.
