Key Calculus Terms and definitions covered in this textbook
  • Arcsecant function

    See Inverse secant function.

  • Back-to-back stemplot

    A stemplot with leaves on either side used to compare two distributions.

  • Bias

    A flaw in the design of a sampling process that systematically causes the sample to differ from the population with respect to the statistic being measured. Undercoverage bias results when the sample systematically excludes one or more segments of the population. Voluntary response bias results when a sample consists only of those who volunteer their responses. Response bias results when the sampling design intentionally or unintentionally influences the responses

  • Cardioid

    A limaçon whose polar equation is r = a ± a sin ?, or r = a ± a cos ?, where a > 0.

  • Constant of variation

    See Power function.

  • Cube root

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

  • Ellipsoid of revolution

    A surface generated by rotating an ellipse about its major axis

  • Equally likely outcomes

    Outcomes of an experiment that have the same probability of occurring.

  • Finite sequence

    A function whose domain is the first n positive integers for some fixed integer n.

  • Inequality

    A statement that compares two quantities using an inequality symbol

  • Interval notation

    Notation used to specify intervals, pp. 4, 5.

  • Inverse function

    The inverse relation of a one-to-one function.

  • Negative association

    A relationship between two variables in which higher values of one variable are generally associated with lower values of the other variable.

  • 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.

  • Probability distribution

    The collection of probabilities of outcomes in a sample space assigned by a probability function.

  • Sinusoidal regression

    A procedure for fitting a curve y = a sin (bx + c) + d to a set of data

  • Standard form of a polynomial function

    ƒ(x) = an x n + an-1x n-1 + Á + a1x + a0

  • Terminal point

    See Arrow.

  • Terminal side of an angle

    See Angle.

  • Upper bound for real zeros

    A number d is an upper bound for the set of real zeros of ƒ if ƒ(x) ? 0 whenever x > d.
