Key Calculus Terms and definitions covered in this textbook
• Complex conjugates

Complex numbers a + bi and a - bi

• Conditional probability

The probability of an event A given that an event B has already occurred

• Determinant

A number that is associated with a square matrix

• Directed distance

See Polar coordinates.

• Equal complex numbers

Complex numbers whose real parts are equal and whose imaginary parts are equal.

• Exponential decay function

Decay modeled by ƒ(x) = a ? bx, a > 0 with 0 < b < 1.

• Exponential growth function

Growth modeled by ƒ(x) = a ? b a > 0, b > 1 .

• Independent variable

Variable representing the domain value of a function (usually x).

• Logarithm

An expression of the form logb x (see Logarithmic function)

• Minute

Angle measure equal to 1/60 of a degree.

• nth power of a

The number with n factors of a , where n is the exponent and a is the base.

• Polynomial in x

An expression that can be written in the form an x n + an-1x n-1 + Á + a1x + a0, where n is a nonnegative integer, the coefficients are real numbers, and an ? 0. The degree of the polynomial is n, the leading coefficient is an, the leading term is anxn, and the constant term is a0. (The number 0 is the zero polynomial)

• Re-expression of data

A transformation of a data set.

• Slope-intercept form (of a line)

y = mx + b

• Solve by substitution

Method for solving systems of linear equations.

• Standard form of a polynomial function

ƒ(x) = an x n + an-1x n-1 + Á + a1x + a0

• Terms of a sequence

The range elements of a sequence.

• Unit vector

Vector of length 1.

• Upper bound for real zeros

A number d is an upper bound for the set of real zeros of ƒ if ƒ(x) ? 0 whenever x > d.

• y-intercept

A point that lies on both the graph and the y-axis.
