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

    An angle whose measure is between 0° and 90°

  • 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

  • Closed interval

    An interval that includes its endpoints

  • Combinations of n objects taken r at a time

    There are nCr = n! r!1n - r2! such combinations,

  • Conditional probability

    The probability of an event A given that an event B has already occurred

  • Decreasing on an interval

    A function f is decreasing on an interval I if, for any two points in I, a positive change in x results in a negative change in ƒ(x)

  • Distance (on a number line)

    The distance between real numbers a and b, or |a - b|

  • Eccentricity

    A nonnegative number that specifies how off-center the focus of a conic is

  • Elementary row operations

    The following three row operations: Multiply all elements of a row by a nonzero constant; interchange two rows; and add a multiple of one row to another row

  • Equation

    A statement of equality between two expressions.

  • Graph of a function ƒ

    The set of all points in the coordinate plane corresponding to the pairs (x, ƒ(x)) for x in the domain of ƒ.

  • Jump discontinuity at x a

    limx:a - ƒ1x2 and limx:a + ƒ1x2 exist but are not equal

  • Length of an arrow

    See Magnitude of an arrow.

  • Limit

    limx:aƒ1x2 = L means that ƒ(x) gets arbitrarily close to L as x gets arbitrarily close (but not equal) to a

  • Perihelion

    The closest point to the Sun in a planet’s orbit.

  • Rational expression

    An expression that can be written as a ratio of two polynomials.

  • Sample survey

    A process for gathering data from a subset of a population, usually through direct questioning.

  • Slope-intercept form (of a line)

    y = mx + b

  • Synthetic division

    A procedure used to divide a polynomial by a linear factor, x - a

  • Upper bound test for real zeros

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