Key Calculus Terms and definitions covered in this textbook
• Algebraic expression

A combination of variables and constants involving addition, subtraction, multiplication, division, powers, and roots

• Domain of a function

The set of all input values for a function

• Elements of a matrix

See Matrix element.

• Feasible points

Points that satisfy the constraints in a linear programming problem.

• 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.

• Horizontal component

See Component form of a vector.

• Inferential statistics

Using the science of statistics to make inferences about the parameters in a population from a sample.

• Limit to growth

See Logistic growth function.

• Local maximum

A value ƒ(c) is a local maximum of ƒ if there is an open interval I containing c such that ƒ(x) < ƒ(c) for all values of x in I

• Logarithmic regression

See Natural logarithmic regression

• Lower bound for real zeros

A number c is a lower bound for the set of real zeros of ƒ if ƒ(x) Z 0 whenever x < c

• Minor axis

The perpendicular bisector of the major axis of an ellipse with endpoints on the ellipse.

• Polynomial function

A function in which ƒ(x)is a polynomial in x, p. 158.

• Positive angle

Angle generated by a counterclockwise rotation.

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.

• Regression model

An equation found by regression and which can be used to predict unknown values.

• Removable discontinuity at x = a

lim x:a- ƒ(x) = limx:a+ ƒ(x) but either the common limit is not equal ƒ(a) to ƒ(a) or is not defined

• Secant

The function y = sec x.

• Sine

The function y = sin x.
