Key Calculus Terms and definitions covered in this textbook
• Additive inverse of a real number

The opposite of b , or -b

• Bias

A flaw in the design of a sampling process that systematically causes the sample to differ from the population with respect to the statistic being measured. Undercoverage bias results when the sample systematically excludes one or more segments of the population. Voluntary response bias results when a sample consists only of those who volunteer their responses. Response bias results when the sampling design intentionally or unintentionally influences the responses

• Binomial coefficients

The numbers in Pascal’s triangle: nCr = anrb = n!r!1n - r2!

• Cosecant

The function y = csc x

• Coterminal angles

Two angles having the same initial side and the same terminal side

• Dot product

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

• Equivalent vectors

Vectors with the same magnitude and direction.

• Extracting square roots

A method for solving equations in the form x 2 = k.

• Matrix, m x n

A rectangular array of m rows and n columns of real numbers

• Multiplication property of inequality

If u < v and c > 0, then uc < vc. If u < and c < 0, then uc > vc

• Multiplicative inverse of a matrix

See Inverse of a matrix

• Multiplicity

The multiplicity of a zero c of a polynomial ƒ(x) of degree n > 0 is the number of times the factor (x - c) (x - z 2) Á (x - z n)

• n-set

A set of n objects.

• Product of functions

(ƒg)(x) = ƒ(x)g(x)

• Range screen

See Viewing window.

• Rectangular coordinate system

See Cartesian coordinate system.

• Series

A finite or infinite sum of terms.

• Solution of a system in two variables

An ordered pair of real numbers that satisfies all of the equations or inequalities in the system

• Synthetic division

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

• Vector equation for a line in space

The line through P0(x 0, y0, z0) in the direction of the nonzero vector V = <a, b, c> has vector equation r = r0 + tv , where r = <x,y,z>.
