Key Calculus Terms and definitions covered in this textbook
• Angular speed

Speed of rotation, typically measured in radians or revolutions per unit time

• Average velocity

The change in position divided by the change in time.

• Dependent event

An event whose probability depends on another event already occurring

• Explanatory variable

A variable that affects a response variable.

• Grapher or graphing utility

Graphing calculator or a computer with graphing software.

• Interval

Connected subset of the real number line with at least two points, p. 4.

• Limaçon

A graph of a polar equation r = a b sin u or r = a b cos u with a > 0 b > 0

• Linear combination of vectors u and v

An expression au + bv , where a and b are real numbers

• Linear system

A system of linear equations

• Polar coordinate system

A coordinate system whose ordered pair is based on the directed distance from a central point (the pole) and the angle measured from a ray from the pole (the polar axis)

• Polar coordinates

The numbers (r, ?) that determine a point’s location in a polar coordinate system. The number r is the directed distance and ? is the directed angle

• Polar form of a complex number

See Trigonometric form of a complex number.

• Power rule of logarithms

logb Rc = c logb R, R 7 0.

• Present value of an annuity T

he net amount of your money put into an annuity.

• Product of complex numbers

(a + bi)(c + di) = (ac - bd) + (ad + bc)i

• Series

A finite or infinite sum of terms.

• Subtraction

a - b = a + (-b)

• 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

• Triangular number

A number that is a sum of the arithmetic series 1 + 2 + 3 + ... + n for some natural number n.

• Trichotomy property

For real numbers a and b, exactly one of the following is true: a < b, a = b , or a > b.
