Key Calculus Terms and definitions covered in this textbook
• Conic section (or conic)

A curve obtained by intersecting a double-napped right circular cone with a plane

• Constraints

See Linear programming problem.

• Explicitly defined sequence

A sequence in which the kth term is given as a function of k.

• Graphical model

A visible representation of a numerical or algebraic model.

• Hyperbola

A set of points in a plane, the absolute value of the difference of whose distances from two fixed points (the foci) is a constant.

• Independent variable

Variable representing the domain value of a function (usually x).

• Inferential statistics

Using the science of statistics to make inferences about the parameters in a population from a sample.

• Lemniscate

A graph of a polar equation of the form r2 = a2 sin 2u or r 2 = a2 cos 2u.

• n factorial

For any positive integer n, n factorial is n! = n.(n - 1) . (n - 2) .... .3.2.1; zero factorial is 0! = 1

• NINT (ƒ(x), x, a, b)

A calculator approximation to ?ab ƒ(x)dx

• Partial fractions

The process of expanding a fraction into a sum of fractions. The sum is called the partial fraction decomposition of the original fraction.

• Placebo

In an experimental study, an inactive treatment that is equivalent to the active treatment in every respect except for the factor about which an inference is to be made. Subjects in a blind experiment do not know if they have been given the active treatment or the placebo.

• Position vector of the point (a, b)

The vector <a,b>.

• Quotient polynomial

See Division algorithm for polynomials.

• Remainder theorem

If a polynomial f(x) is divided by x - c , the remainder is ƒ(c)

• Repeated zeros

Zeros of multiplicity ? 2 (see Multiplicity).

• Scientific notation

A positive number written as c x 10m, where 1 ? c < 10 and m is an integer.

• Summation notation

The series a nk=1ak, where n is a natural number ( or ?) is in summation notation and is read "the sum of ak from k = 1 to n(or infinity).” k is the index of summation, and ak is the kth term of the series

• Venn diagram

A visualization of the relationships among events within a sample space.

• Vertex of an angle

See Angle.
