Key Calculus Terms and definitions covered in this textbook
• Average rate of change of ƒ over [a, b]

The number ƒ(b) - ƒ(a) b - a, provided a ? b.

• Control

The principle of experimental design that makes it possible to rule out other factors when making inferences about a particular explanatory variable

• 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>

• Factor

In algebra, a quantity being multiplied in a product. In statistics, a potential explanatory variable under study in an experiment, .

• Gaussian elimination

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

• Inductive step

See Mathematical induction.

• Interval

Connected subset of the real number line with at least two points, p. 4.

• Inverse tangent function

The function y = tan-1 x

• kth term of a sequence

The kth expression in the sequence

• Multiplication principle of probability

If A and B are independent events, then P(A and B) = P(A) # P(B). If Adepends on B, then P(A and B) = P(A|B) # P(B)

• Power regression

A procedure for fitting a curve y = a . x b to a set of data.

• Power rule of logarithms

logb Rc = c logb R, R 7 0.

An equation that can be written in the form ax 2 + bx + c = 01a ? 02

The distance from a point on a circle (or a sphere) to the center of the circle (or the sphere).

• Real number line

A horizontal line that represents the set of real numbers.

• Sample survey

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

• Sum of functions

(ƒ + g)(x) = ƒ(x) + g(x)

• Terms of a sequence

The range elements of a sequence.

• Vertical line

x = a.

• Vertices of a hyperbola

The points where a hyperbola intersects the line containing its foci.
