Key Calculus Terms and definitions covered in this textbook
• Angle

Union of two rays with a common endpoint (the vertex). The beginning ray (the initial side) can be rotated about its endpoint to obtain the final position (the terminal side)

• Angle of depression

The acute angle formed by the line of sight (downward) and the horizontal

• Average velocity

The change in position divided by the change in time.

• Combinations of n objects taken r at a time

There are nCr = n! r!1n - r2! such combinations,

• Constraints

See Linear programming problem.

• Distance (in Cartesian space)

The distance d(P, Q) between and P(x, y, z) and Q(x, y, z) or d(P, Q) ((x ) - x 2)2 + (y1 - y2)2 + (z 1 - z 2)2

• Half-plane

The graph of the linear inequality y ? ax + b, y > ax + b y ? ax + b, or y < ax + b.

• Irreducible quadratic over the reals

A quadratic polynomial with real coefficients that cannot be factored using real coefficients.

• Linear function

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

• Pascal’s triangle

A number pattern in which row n (beginning with n = 02) consists of the coefficients of the expanded form of (a+b)n.

• Permutations of n objects taken r at a time

There are nPr = n!1n - r2! such permutations

• Positive angle

Angle generated by a counterclockwise rotation.

• Quotient of complex numbers

a + bi c + di = ac + bd c2 + d2 + bc - ad c2 + d2 i

• Right-hand limit of ƒ at x a

The limit of ƒ as x approaches a from the right.

• Standard form: equation of a circle

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

• Tangent

The function y = tan x

• Unit circle

A circle with radius 1 centered at the origin.

• Vertex form for a quadratic function

ƒ(x) = a(x - h)2 + k

• Weighted mean

A mean calculated in such a way that some elements of the data set have higher weights (that is, are counted more strongly in determining the mean) than others.

• Yscl

The scale of the tick marks on the y-axis in a viewing window.
