Key Calculus Terms and definitions covered in this textbook
• Absolute value of a complex number

The absolute value of the complex number z = a + b is given by ?a2+b2; also, the length of the segment from the origin to z in the complex plane.

• Aphelion

The farthest point from the Sun in a planet’s orbit

• Blind experiment

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

• Combinatorics

A branch of mathematics related to determining the number of elements of a set or the number of ways objects can be arranged or combined

• Common logarithm

A logarithm with base 10.

• Deductive reasoning

The process of utilizing general information to prove a specific hypothesis

• Division algorithm for polynomials

Given ƒ(x), d(x) ? 0 there are unique polynomials q1x (quotient) and r1x(remainder) ƒ1x2 = d1x2q1x2 + r1x2 with with either r1x2 = 0 or degree of r(x) 6 degree of d1x2

• Dot product

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

• Equilibrium price

See Equilibrium point.

• Event

A subset of a sample space.

• Leibniz notation

The notation dy/dx for the derivative of ƒ.

• n-set

A set of n objects.

• Ordered pair

A pair of real numbers (x, y), p. 12.

• Paraboloid of revolution

A surface generated by rotating a parabola about its line of symmetry.

• Polar coordinates

The numbers (r, ?) that determine a point’s location in a polar coordinate system. The number r is the directed distance and ? is the directed angle

• Polynomial function

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

• Reflexive property of equality

a = a

• Standard form of a polynomial function

ƒ(x) = an x n + an-1x n-1 + Á + a1x + a0

• 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.

• Yscl

The scale of the tick marks on the y-axis in a viewing window.
