Key Calculus Terms and definitions covered in this textbook
• Absolute value of a vector

See Magnitude of a vector.

P(A or B) = P(A) + P(B) - P(A and B). If A and B are mutually exclusive events, then P(A or B) = P(A) + P(B)

• Arctangent function

See Inverse tangent function.

• Constant term

See Polynomial function

• Convergence of a sequence

A sequence {an} converges to a if limn: q an = a

• Distance (in a coordinate plane)

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

• equation of an ellipse

(x - h2) a2 + (y - k)2 b2 = 1 or (y - k)2 a2 + (x - h)2 b2 = 1

• Equilibrium price

See Equilibrium point.

• Fitting a line or curve to data

Finding a line or curve that comes close to passing through all the points in a scatter plot.

• Focal axis

The line through the focus and perpendicular to the directrix of a conic.

• Frequency table (in statistics)

A table showing frequencies.

• Horizontal Line Test

A test for determining whether the inverse of a relation is a function.

• Length of a vector

See Magnitude of a vector.

• Ordinary annuity

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

• Range screen

See Viewing window.

• Reference triangle

For an angle ? in standard position, a reference triangle is a triangle formed by the terminal side of angle ?, the x-axis, and a perpendicular dropped from a point on the terminal side to the x-axis. The angle in a reference triangle at the origin is the reference angle

• Relation

A set of ordered pairs of real numbers.

• Right angle

A 90° angle.

• Series

A finite or infinite sum of terms.

• Standard form of a complex number

a + bi, where a and b are real numbers
