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

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

  • Algebraic expression

    A combination of variables and constants involving addition, subtraction, multiplication, division, powers, and roots

  • Census

    An observational study that gathers data from an entire population

  • De Moivre’s theorem

    (r(cos ? + i sin ?))n = r n (cos n? + i sin n?)

  • Extraneous solution

    Any solution of the resulting equation that is not a solution of the original equation.

  • Graph of parametric equations

    The set of all points in the coordinate plane corresponding to the ordered pairs determined by the parametric equations.

  • Inductive step

    See Mathematical induction.

  • Irrational zeros

    Zeros of a function that are irrational numbers.

  • Linear equation in x

    An equation that can be written in the form ax + b = 0, where a and b are real numbers and a Z 0

  • Major axis

    The line segment through the foci of an ellipse with endpoints on the ellipse

  • Opens upward or downward

    A parabola y = ax 2 + bx + c opens upward if a > 0 and opens downward if a < 0.

  • Periodic function

    A function ƒ for which there is a positive number c such that for every value t in the domain of ƒ. The smallest such number c is the period of the function.

  • Placebo

    In an experimental study, an inactive treatment that is equivalent to the active treatment in every respect except for the factor about which an inference is to be made. Subjects in a blind experiment do not know if they have been given the active treatment or the placebo.

  • Probability distribution

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

  • Random variable

    A function that assigns real-number values to the outcomes in a sample space.

  • Recursively defined sequence

    A sequence defined by giving the first term (or the first few terms) along with a procedure for finding the subsequent terms.

  • Simple harmonic motion

    Motion described by d = a sin wt or d = a cos wt

  • Solve by elimination or substitution

    Methods for solving systems of linear equations.

  • Statistic

    A number that measures a quantitative variable for a sample from a population.

  • System

    A set of equations or inequalities.
