Key Calculus Terms and definitions covered in this textbook
• Census

An observational study that gathers data from an entire population

• Convergence of a series

A series aqk=1 ak converges to a sum S if imn: q ank=1ak = S

• Dependent variable

Variable representing the range value of a function (usually y)

• Graph of parametric equations

The set of all points in the coordinate plane corresponding to the ordered pairs determined by the parametric equations.

• Histogram

A graph that visually represents the information in a frequency table using rectangular areas proportional to the frequencies.

• Horizontal asymptote

The line is a horizontal asymptote of the graph of a function ƒ if lim x:- q ƒ(x) = or lim x: q ƒ(x) = b

• Integers

The numbers . . ., -3, -2, -1, 0,1,2,...2

• 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

• Mathematical model

A mathematical structure that approximates phenomena for the purpose of studying or predicting their behavior

• Negative linear correlation

See Linear correlation.

• nth power of a

The number with n factors of a , where n is the exponent and a is the base.

• Ordinary annuity

An annuity in which deposits are made at the same time interest is posted.

• 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

• Projectile motion

The movement of an object that is subject only to the force of gravity

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.

• Reflection through the origin

x, y and (-x,-y) are reflections of each other through the origin.

• 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

• Translation

See Horizontal translation, Vertical translation.

• Velocity

A vector that specifies the motion of an object in terms of its speed and direction.

• z-axis

Usually the third dimension in Cartesian space.
