Key Calculus Terms and definitions covered in this textbook
• Bearing

Measure of the clockwise angle that the line of travel makes with due north

• Blind experiment

An experiment in which subjects do not know if they have been given an active treatment or a placebo

• Constraints

See Linear programming problem.

• Distributive property

a(b + c) = ab + ac and related properties

• Exponential function

A function of the form ƒ(x) = a ? bx,where ?0, b > 0 b ?1

• Graph of a polar equation

The set of all points in the polar coordinate system corresponding to the ordered pairs (r,?) that are solutions of the polar equation.

• Implicitly defined function

A function that is a subset of a relation defined by an equation in x and y.

• Magnitude of a real number

See Absolute value of a real number

• Main diagonal

The diagonal from the top left to the bottom right of a square matrix

• Natural logarithmic regression

A procedure for fitting a logarithmic curve to a set of data.

• Parametrization

A set of parametric equations for a curve.

• Right angle

A 90° angle.

• Series

A finite or infinite sum of terms.

• Slope-intercept form (of a line)

y = mx + b

• Solve algebraically

Use an algebraic method, including paper and pencil manipulation and obvious mental work, with no calculator or grapher use. When appropriate, the final exact solution may be approximated by a calculator

• Standard deviation

A measure of how a data set is spread

• Transformation

A function that maps real numbers to real numbers.

• Vertices of a hyperbola

The points where a hyperbola intersects the line containing its foci.

• Weighted mean

A mean calculated in such a way that some elements of the data set have higher weights (that is, are counted more strongly in determining the mean) than others.

• Zoom out

A procedure of a graphing utility used to view more of the coordinate plane (used, for example, to find theend behavior of a function).
