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)

• Blind experiment

An experiment in which subjects do not know if they have been given an active treatment or a placebo

• Cube root

nth root, where n = 3 (see Principal nth root),

• Directed line segment

See Arrow.

• Equivalent vectors

Vectors with the same magnitude and direction.

• Event

A subset of a sample space.

• Explicitly defined sequence

A sequence in which the kth term is given as a function of k.

• Head minus tail (HMT) rule

An arrow with initial point (x1, y1 ) and terminal point (x2, y2) represents the vector <8x 2 - x 1, y2 - y19>

• Identity

An equation that is always true throughout its domain.

• Infinite discontinuity at x = a

limx:a + x a ƒ(x) = q6 or limx:a - ƒ(x) = q.

• Inverse reflection principle

If the graph of a relation is reflected across the line y = x , the graph of the inverse relation results.

• Law of cosines

a2 = b2 + c2 - 2bc cos A, b2 = a2 + c2 - 2ac cos B, c2 = a2 + b2 - 2ab cos C

• 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

• PH

The measure of acidity

• Positive angle

Angle generated by a counterclockwise rotation.

• Projection of u onto v

The vector projv u = au # vƒvƒb2v

• Range screen

See Viewing window.

• Reflection across the x-axis

x, y and (x,-y) are reflections of each other across the x-axis.

• Right triangle

A triangle with a 90° angle.

• Unit vector

Vector of length 1.
