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

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

• Complex number

An expression a + bi, where a (the real part) and b (the imaginary part) are real numbers

• Correlation coefficient

A measure of the strength of the linear relationship between two variables, pp. 146, 162.

• Directed angle

See Polar coordinates.

• Directrix of a parabola, ellipse, or hyperbola

A line used to determine the conic

• equation of a hyperbola

(x - h)2 a2 - (y - k)2 b2 = 1 or (y - k)2 a2 - (x - h)2 b2 = 1

• Extracting square roots

A method for solving equations in the form x 2 = k.

• Factored form

The left side of u(v + w) = uv + uw.

• Finite series

Sum of a finite number of terms.

• Identity matrix

A square matrix with 1’s in the main diagonal and 0’s elsewhere, p. 534.

• Inverse properties

a + 1-a2 = 0, a # 1a

• Inverse variation

See Power function.

• Linear correlation

A scatter plot with points clustered along a line. Correlation is positive if the slope is positive and negative if the slope is negative

• Mapping

A function viewed as a mapping of the elements of the domain onto the elements of the range

• One-to-one rule of exponents

x = y if and only if bx = by.

• Placebo

In an experimental study, an inactive treatment that is equivalent to the active treatment in every respect except for the factor about which an inference is to be made. Subjects in a blind experiment do not know if they have been given the active treatment or the placebo.

• Power function

A function of the form ƒ(x) = k . x a, where k and a are nonzero constants. k is the constant of variation and a is the power.

• Sample standard deviation

The standard deviation computed using only a sample of the entire population.

• Scientific notation

A positive number written as c x 10m, where 1 ? c < 10 and m is an integer.

• Slope-intercept form (of a line)

y = mx + b
