Key Calculus Terms and definitions covered in this textbook
• Angular speed

Speed of rotation, typically measured in radians or revolutions per unit time

• Explicitly defined sequence

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

• First-degree equation in x , y, and z

An equation that can be written in the form.

• Fitting a line or curve to data

Finding a line or curve that comes close to passing through all the points in a scatter plot.

• Independent variable

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

• Mapping

A function viewed as a mapping of the elements of the domain onto the elements of the range

• Midpoint (on a number line)

For the line segment with endpoints a and b, a + b2

• nth power of a

The number with n factors of a , where n is the exponent and a is the base.

• Open interval

An interval that does not include its endpoints.

• Ordered pair

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

• Parabola

The graph of a quadratic function, or the set of points in a plane that are equidistant from a fixed point (the focus) and a fixed line (the directrix).

• Projection of u onto v

The vector projv u = au # vƒvƒb2v

A function that can be written in the form ƒ(x) = ax 2 + bx + c, where a, b, and c are real numbers, and a ? 0.

The graph in three dimensions of a seconddegree equation in three variables.

• Rectangular coordinate system

See Cartesian coordinate system.

• Replication

The principle of experimental design that minimizes the effects of chance variation by repeating the experiment multiple times.

• 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.

• Solution set of an inequality

The set of all solutions of an inequality

• Square matrix

A matrix whose number of rows equals the number of columns.

• Standard form of a polar equation of a conic

r = ke 1 e cos ? or r = ke 1 e sin ? ,
