Key Calculus Terms and definitions covered in this textbook
• Additive inverse of a complex number

The opposite of a + bi, or -a - bi

• Axis of symmetry

See Line of symmetry.

• Constant function (on an interval)

ƒ(x 1) = ƒ(x 2) x for any x1 and x2 (in the interval)

• Ellipsoid of revolution

A surface generated by rotating an ellipse about its major axis

• Focal width of a parabola

The length of the chord through the focus and perpendicular to the axis.

• Focus, foci

See Ellipse, Hyperbola, Parabola.

• Frequency

Reciprocal of the period of a sinusoid.

• Grapher or graphing utility

Graphing calculator or a computer with graphing software.

• Identity properties

a + 0 = a, a ? 1 = a

• 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.

• Quotient of functions

a ƒ g b(x) = ƒ(x) g(x) , g(x) ? 0

• Quotient polynomial

See Division algorithm for polynomials.

• Remainder theorem

If a polynomial f(x) is divided by x - c , the remainder is ƒ(c)

• Sinusoidal regression

A procedure for fitting a curve y = a sin (bx + c) + d to a set of data

• Statute mile

5280 feet.

• Sum of two vectors

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

• Terminal point

See Arrow.

• Transitive property

If a = b and b = c , then a = c. Similar properties hold for the inequality symbols <, >, ?, ?.

• Unit circle

A circle with radius 1 centered at the origin.

• Zero vector

The vector <0,0> or <0,0,0>.
