Key Calculus Terms and definitions covered in this textbook
  • Absolute minimum

    A value ƒ(c) is an absolute minimum value of ƒ if ƒ(c) ? ƒ(x)for all x in the domain of ƒ.

  • Annuity

    A sequence of equal periodic payments.

  • Characteristic polynomial of a square matrix A

    det(xIn - A), where A is an n x n matrix

  • Convenience sample

    A sample that sacrifices randomness for convenience

  • Cube root

    nth root, where n = 3 (see Principal nth root),

    The number of individuals or observations with a certain characteristic.

  • Histogram

    A graph that visually represents the information in a frequency table using rectangular areas proportional to the frequencies.

  • Slope-intercept form (of a line)

    y = mx + b

  • Solution set of an inequality

    The set of all solutions of an inequality

  • symmetric about the x-axis

    A graph in which (x, -y) is on the graph whenever (x, y) is; or a graph in which (r, -?) or (-r, ?, -?) is on the graph whenever (r, ?) is

  • Union of two sets A and B

    The set of all elements that belong to A or B or both.
