Key Calculus Terms and definitions covered in this textbook
• Bearing

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

• Boundary

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

• Categorical variable

In statistics, a nonnumerical variable such as gender or hair color. Numerical variables like zip codes, in which the numbers have no quantitative significance, are also considered to be categorical.

• Derivative of ƒ at x a

ƒ'(a) = lim x:a ƒ(x) - ƒ(a) x - a provided the limit exists

• Difference of complex numbers

(a + bi) - (c + di) = (a - c) + (b - d)i

• Finite series

Sum of a finite number of terms.

• 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.

• Horizontal line

y = b.

• Initial point

See Arrow.

• Initial value of a function

ƒ 0.

• Irrational numbers

Real numbers that are not rational, p. 2.

• Logarithmic function with base b

The inverse of the exponential function y = bx, denoted by y = logb x

• Negative linear correlation

See Linear correlation.

• Negative numbers

Real numbers shown to the left of the origin on a number line.

• Octants

The eight regions of space determined by the coordinate planes.

• Polar form of a complex number

See Trigonometric form of a complex number.

• Positive numbers

Real numbers shown to the right of the origin on a number line.

• Standard form: equation of a circle

(x - h)2 + (y - k2) = r 2

• Summation notation

The series a nk=1ak, where n is a natural number ( or ?) is in summation notation and is read "the sum of ak from k = 1 to n(or infinity).” k is the index of summation, and ak is the kth term of the series

• Zero factor property

If ab = 0 , then either a = 0 or b = 0.
