Key Calculus Terms and definitions covered in this textbook
  • Acute angle

    An angle whose measure is between 0° and 90°

  • Bounded

    A function is bounded if there are numbers b and B such that b ? ƒ(x) ? B for all x in the domain of f.

  • Center

    The central point in a circle, ellipse, hyperbola, or sphere

  • Identity function

    The function ƒ(x) = x.

  • Inverse secant function

    The function y = sec-1 x

  • Limit to growth

    See Logistic growth function.

  • Linear correlation

    A scatter plot with points clustered along a line. Correlation is positive if the slope is positive and negative if the slope is negative

  • Linear function

    A function that can be written in the form ƒ(x) = mx + b, where and b are real numbers

  • Logarithm

    An expression of the form logb x (see Logarithmic function)

  • Maximum r-value

    The value of |r| at the point on the graph of a polar equation that has the maximum distance from the pole

  • Order of magnitude (of n)

    log n.

  • Orthogonal vectors

    Two vectors u and v with u x v = 0.

  • Perpendicular lines

    Two lines that are at right angles to each other

  • Quotient rule of logarithms

    logb a R S b = logb R - logb S, R > 0, S > 0

  • Reciprocal identity

    An identity that equates a trigonometric function with the reciprocal of another trigonometricfunction.

  • Second

    Angle measure equal to 1/60 of a minute.

  • Sequence

    See Finite sequence, Infinite sequence.

  • Stemplot (or stem-and-leaf plot)

    An arrangement of a numerical data set into a specific tabular format.

  • 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.

  • Upper bound test for real zeros

    A test for finding an upper bound for the real zeros of a polynomial.
