Key Calculus Terms and definitions covered in this textbook
  • Combination

    An arrangement of elements of a set, in which order is not important

  • Combinatorics

    A branch of mathematics related to determining the number of elements of a set or the number of ways objects can be arranged or combined

  • Continuous at x = a

    lim x:a x a ƒ(x) = ƒ(a)

  • Cubic

    A degree 3 polynomial function

  • Derivative of ƒ at x a

    ƒ'(a) = lim x:a ƒ(x) - ƒ(a) x - a provided the limit exists

  • Geometric series

    A series whose terms form a geometric sequence.

  • Horizontal translation

    A shift of a graph to the left or right.

  • Increasing on an interval

    A function ƒ is increasing on an interval I if, for any two points in I, a positive change in x results in a positive change in.

  • Initial side of an angle

    See Angle.

  • Inverse sine function

    The function y = sin-1 x

  • Linear regression

    A procedure for finding the straight line that is the best fit for the data

  • Observational study

    A process for gathering data from a subset of a population through current or past observations. This differs from an experiment in that no treatment is imposed.

  • Opposite

    See Additive inverse of a real number and Additive inverse of a complex number.

  • Paraboloid of revolution

    A surface generated by rotating a parabola about its line of symmetry.

  • Pythagorean identities

    sin2 u + cos2 u = 1, 1 + tan2 u = sec2 u, and 1 + cot2 u = csc2 u

  • Rectangular coordinate system

    See Cartesian coordinate system.

  • Right circular cone

    The surface created when a line is rotated about a second line that intersects but is not perpendicular to the first line.

  • Standard deviation

    A measure of how a data set is spread

  • Variance

    The square of the standard deviation.

  • Window dimensions

    The restrictions on x and y that specify a viewing window. See Viewing window.
