Key Calculus Terms and definitions covered in this textbook
• Bar chart

A rectangular graphical display of categorical data.

• Central angle

An angle whose vertex is the center of a circle

• Complex plane

A coordinate plane used to represent the complex numbers. The x-axis of the complex plane is called the real axis and the y-axis is the imaginary axis

• Direction of an arrow

The angle the arrow makes with the positive x-axis

• Ellipse

The set of all points in the plane such that the sum of the distances from a pair of fixed points (the foci) is a constant

• Integers

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

• Inverse cotangent function

The function y = cot-1 x

• Inverse relation (of the relation R)

A relation that consists of all ordered pairs b, a for which a, b belongs to R.

• Irrational numbers

Real numbers that are not rational, p. 2.

• Linear combination of vectors u and v

An expression au + bv , where a and b are real numbers

A measure that tells how widely distributed data are.

• Monomial function

A polynomial with exactly one term.

• Polar distance formula

The distance between the points with polar coordinates (r1, ?1 ) and (r2, ?2 ) = 2r 12 + r 22 - 2r1r2 cos 1?1 - ?22

• Probability distribution

The collection of probabilities of outcomes in a sample space assigned by a probability function.

• Proportional

See Power function

• Rational expression

An expression that can be written as a ratio of two polynomials.

• 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

• Sum of two vectors

<u1, u2> + <v1, v2> = <u1 + v1, u2 + v2> <u1 + v1, u2 + v2, u3 + v3>

• Work

The product of a force applied to an object over a given distance W = ƒFƒ ƒAB!ƒ.

• z-axis

Usually the third dimension in Cartesian space.
