Key Calculus Terms and definitions covered in this textbook
• Components of a vector

See Component form of a vector.

• Damping factor

The factor Ae-a in an equation such as y = Ae-at cos bt

• Expanded form of a series

A series written explicitly as a sum of terms (not in summation notation).

• Explanatory variable

A variable that affects a response variable.

• Logarithmic form

An equation written with logarithms instead of exponents

• Magnitude of a real number

See Absolute value of a real number

• Numerical derivative of ƒ at a

NDER f(a) = ƒ1a + 0.0012 - ƒ1a - 0.00120.002

• Permutations of n objects taken r at a time

There are nPr = n!1n - r2! such permutations

• Polar axis

See Polar coordinate system.

• Power regression

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

The formula x = -b 2b2 - 4ac2a used to solve ax 2 + bx + c = 0.

• Quantitative variable

A variable (in statistics) that takes on numerical values for a characteristic being measured.

• Randomization

The principle of experimental design that makes it possible to use the laws of probability when making inferences.

• Relation

A set of ordered pairs of real numbers.

• RRAM

A Riemann sum approximation of the area under a curve ƒ(x) from x = a to x = b using x1 as the right-hand end point of each subinterval.

• Sinusoid

A function that can be written in the form f(x) = a sin (b (x - h)) + k or f(x) = a cos (b(x - h)) + k. The number a is the amplitude, and the number h is the phase shift.

A graph in which (-x, -y) is on the the graph whenever (x, y) is; or a graph in which (-r, ?) or (r, ? + ?) is on the graph whenever (r, ?) is

• Window dimensions

The restrictions on x and y that specify a viewing window. See Viewing window.

• z-coordinate

The directed distance from the xy-plane to a point in space, or the third number in an ordered triple.

• Zero matrix

A matrix consisting entirely of zeros.
