Key Calculus Terms and definitions covered in this textbook
• Acute angle

An angle whose measure is between 0° and 90°

• Bounded

A function is bounded if there are numbers b and B such that b ? ƒ(x) ? B for all x in the domain of f.

• Center

The central point in a circle, ellipse, hyperbola, or sphere

• Identity function

The function ƒ(x) = x.

• Inverse secant function

The function y = sec-1 x

• Limit to growth

See Logistic growth function.

• Linear correlation

A scatter plot with points clustered along a line. Correlation is positive if the slope is positive and negative if the slope is negative

• Linear function

A function that can be written in the form ƒ(x) = mx + b, where and b are real numbers

• Logarithm

An expression of the form logb x (see Logarithmic function)

• Maximum r-value

The value of |r| at the point on the graph of a polar equation that has the maximum distance from the pole

• Order of magnitude (of n)

log n.

• Orthogonal vectors

Two vectors u and v with u x v = 0.

• Perpendicular lines

Two lines that are at right angles to each other

• Quotient rule of logarithms

logb a R S b = logb R - logb S, R > 0, S > 0

• Reciprocal identity

An identity that equates a trigonometric function with the reciprocal of another trigonometricfunction.

• Second

Angle measure equal to 1/60 of a minute.

• Sequence

See Finite sequence, Infinite sequence.

• Stemplot (or stem-and-leaf plot)

An arrangement of a numerical data set into a specific tabular format.

• Upper bound for real zeros

A number d is an upper bound for the set of real zeros of ƒ if ƒ(x) ? 0 whenever x > d.

• Upper bound test for real zeros

A test for finding an upper bound for the real zeros of a polynomial.
