Key Calculus Terms and definitions covered in this textbook
• Bearing

Measure of the clockwise angle that the line of travel makes with due north

• Bounded below

A function is bounded below if there is a number b such that b ? ƒ(x) for all x in the domain of f.

• Equilibrium point

A point where the supply curve and demand curve intersect. The corresponding price is the equilibrium price.

• Equivalent vectors

Vectors with the same magnitude and direction.

• Even function

A function whose graph is symmetric about the y-axis for all x in the domain of ƒ.

• Frequency (in statistics)

The number of individuals or observations with a certain characteristic.

• Histogram

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

• Initial point

See Arrow.

• Integers

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

• Linear inequality in x

An inequality that can be written in the form ax + b < 0 ,ax + b … 0 , ax + b > 0, or ax + b Ú 0, where a and b are real numbers and a Z 0

• Linear system

A system of linear equations

• Magnitude of an arrow

The magnitude of PQ is the distance between P and Q

• NINT (ƒ(x), x, a, b)

A calculator approximation to ?ab ƒ(x)dx

• Open interval

An interval that does not include its endpoints.

An equation that can be written in the form ax 2 + bx + c = 01a ? 02

• Quartile

The first quartile is the median of the lower half of a set of data, the second quartile is the median, and the third quartile is the median of the upper half of the data.

• Reflexive property of equality

a = a

• Rose curve

A graph of a polar equation or r = a cos nu.

• Sum of complex numbers

(a + bi) + (c + di) = (a + c) + (b + d)i
