Key Calculus Terms and definitions covered in this textbook
  • Addition principle of probability.

    P(A or B) = P(A) + P(B) - P(A and B). If A and B are mutually exclusive events, then P(A or B) = P(A) + P(B)

  • Blocking

    A feature of some experimental designs that controls for potential differences between subject groups by applying treatments randomly within homogeneous blocks of subjects

  • Bounded interval

    An interval that has finite length (does not extend to ? or -?)

  • Constraints

    See Linear programming problem.

  • Correlation coefficient

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

  • Descriptive statistics

    The gathering and processing of numerical information

  • equation of an ellipse

    (x - h2) a2 + (y - k)2 b2 = 1 or (y - k)2 a2 + (x - h)2 b2 = 1

  • Horizontal line

    y = b.

  • Identity

    An equation that is always true throughout its domain.

  • Inferential statistics

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

  • Line of travel

    The path along which an object travels

  • Multiplicative inverse of a complex number

    The reciprocal of a + bi, or 1 a + bi = a a2 + b2- ba2 + b2 i

  • Pascal’s triangle

    A number pattern in which row n (beginning with n = 02) consists of the coefficients of the expanded form of (a+b)n.

  • 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.

  • Riemann sum

    A sum where the interval is divided into n subintervals of equal length and is in the ith subinterval.

  • Row echelon form

    A matrix in which rows consisting of all 0’s occur only at the bottom of the matrix, the first nonzero entry in any row with nonzero entries is 1, and the leading 1’s move to the right as we move down the rows.

  • Semiperimeter of a triangle

    One-half of the sum of the lengths of the sides of a triangle.

  • Slant asymptote

    An end behavior asymptote that is a slant line

  • Solution set of an inequality

    The set of all solutions of an inequality

  • Third quartile

    See Quartile.
