Key Calculus Terms and definitions covered in this textbook
• Algebraic expression

A combination of variables and constants involving addition, subtraction, multiplication, division, powers, and roots

• Argument of a complex number

The argument of a + bi is the direction angle of the vector {a,b}.

• Compound fraction

A fractional expression in which the numerator or denominator may contain fractions

• Damping factor

The factor Ae-a in an equation such as y = Ae-at cos bt

• Data

Facts collected for statistical purposes (singular form is datum)

• De Moivre’s theorem

(r(cos ? + i sin ?))n = r n (cos n? + i sin n?)

• Dependent variable

Variable representing the range value of a function (usually y)

• Determinant

A number that is associated with a square matrix

• Jump discontinuity at x a

limx:a - ƒ1x2 and limx:a + ƒ1x2 exist but are not equal

• Law of cosines

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

• Linear factorization theorem

A polynomial ƒ(x) of degree n > 0 has the factorization ƒ(x) = a(x1 - z1) 1x - i z 22 Á 1x - z n where the z1 are the zeros of ƒ

• Measure of an angle

The number of degrees or radians in an angle

• Minor axis

• Parameter interval

See Parametric equations.

• Quotient of functions

a ƒ g b(x) = ƒ(x) g(x) , g(x) ? 0

• Right angle

A 90° angle.

• Stem

The initial digit or digits of a number in a stemplot.

• x-coordinate

The directed distance from the y-axis yz-plane to a point in a plane (space), or the first number in an ordered pair (triple), pp. 12, 629.

• z-axis

Usually the third dimension in Cartesian space.

• Zero matrix

A matrix consisting entirely of zeros.
