Key Calculus Terms and definitions covered in this textbook
• Angle of depression

The acute angle formed by the line of sight (downward) and the horizontal

• Annual percentage yield (APY)

The rate that would give the same return if interest were computed just once a year

• Categorical variable

In statistics, a nonnumerical variable such as gender or hair color. Numerical variables like zip codes, in which the numbers have no quantitative significance, are also considered to be categorical.

• Coefficient matrix

A matrix whose elements are the coefficients in a system of linear equations

• Complex number

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

• Dependent event

An event whose probability depends on another event already occurring

• General form (of a line)

Ax + By + C = 0, where A and B are not both zero.

• Horizontal Line Test

A test for determining whether the inverse of a relation is a function.

• Inferential statistics

Using the science of statistics to make inferences about the parameters in a population from a sample.

• Leaf

The final digit of a number in a stemplot.

• Logarithmic re-expression of data

Transformation of a data set involving the natural logarithm: exponential regression, natural logarithmic regression, power regression

• LRAM

A Riemann sum approximation of the area under a curve ƒ(x) from x = a to x = b using x1 as the left-hand endpoint of each subinterval

• Main diagonal

The diagonal from the top left to the bottom right of a square matrix

• NDER ƒ(a)

See Numerical derivative of ƒ at x = a.

• Order of an m x n matrix

The order of an m x n matrix is m x n.

• Origin

The number zero on a number line, or the point where the x- and y-axes cross in the Cartesian coordinate system, or the point where the x-, y-, and z-axes cross in Cartesian three-dimensional space

• Power rule of logarithms

logb Rc = c logb R, R 7 0.

• Projection of u onto v

The vector projv u = au # vƒvƒb2v

• Stemplot (or stem-and-leaf plot)

An arrangement of a numerical data set into a specific tabular format.

• Sum of an infinite geometric series

Sn = a 1 - r , |r| 6 1
