Key Calculus Terms and definitions covered in this textbook
• Arc length formula

The length of an arc in a circle of radius r intercepted by a central angle of u radians is s = r u.

• Boundary

The set of points on the “edge” of a region

• Control

The principle of experimental design that makes it possible to rule out other factors when making inferences about a particular explanatory variable

• Correlation coefficient

A measure of the strength of the linear relationship between two variables, pp. 146, 162.

• Event

A subset of a sample space.

• Expanded form of a series

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

• Factor

In algebra, a quantity being multiplied in a product. In statistics, a potential explanatory variable under study in an experiment, .

• Frequency

Reciprocal of the period of a sinusoid.

• Infinite discontinuity at x = a

limx:a + x a ƒ(x) = q6 or limx:a - ƒ(x) = q.

• Intercepted arc

Arc of a circle between the initial side and terminal side of a central angle.

• Length of an arrow

See Magnitude of an arrow.

• Line of symmetry

A line over which a graph is the mirror image of itself

• Midpoint (in Cartesian space)

For the line segment with endpoints (x 1, y1, z 1) and (x2, y2, z2), ax 1 + x 22 ,y1 + y22 ,z 1 + z 22 b

• Ordered set

A set is ordered if it is possible to compare any two elements and say that one element is “less than” or “greater than” the other.

• Resolving a vector

Finding the horizontal and vertical components of a vector.

• Right circular cone

The surface created when a line is rotated about a second line that intersects but is not perpendicular to the first line.

• 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.

• Sinusoidal regression

A procedure for fitting a curve y = a sin (bx + c) + d to a set of data

• Term of a polynomial (function)

An expression of the form anxn in a polynomial (function).

• Variance

The square of the standard deviation.
