Key Calculus Terms and definitions covered in this textbook
• Blind experiment

An experiment in which subjects do not know if they have been given an active treatment or a placebo

• Combination

An arrangement of elements of a set, in which order is not important

• Endpoint of an interval

A real number that represents one “end” of an interval.

• Increasing on an interval

A function ƒ is increasing on an interval I if, for any two points in I, a positive change in x results in a positive change in.

• Inverse reflection principle

If the graph of a relation is reflected across the line y = x , the graph of the inverse relation results.

• Main diagonal

The diagonal from the top left to the bottom right of a square matrix

• Modified boxplot

A boxplot with the outliers removed.

• 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)

• Octants

The eight regions of space determined by the coordinate planes.

• Polynomial function

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

• Random variable

A function that assigns real-number values to the outcomes in a sample space.

• Reciprocal of a real number

See Multiplicative inverse of a real number.

• Simple harmonic motion

Motion described by d = a sin wt or d = a cos wt

• Solution set of an inequality

The set of all solutions of an inequality

• Sphere

A set of points in Cartesian space equally distant from a fixed point called the center.

• Sum of a finite geometric series

Sn = a111 - r n 2 1 - r

• Tangent line of ƒ at x = a

The line through (a, ƒ(a)) with slope ƒ'(a) provided ƒ'(a) exists.

• Vertices of a hyperbola

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

• yz-plane

The points (0, y, z) in Cartesian space.

• Zero vector

The vector <0,0> or <0,0,0>.
