Key Calculus Terms and definitions covered in this textbook
  • Angle between vectors

    The angle formed by two nonzero vectors sharing a common initial point

  • Arrow

    The notation PQ denoting the directed line segment with initial point P and terminal point Q.

  • Binomial probability

    In an experiment with two possible outcomes, the probability of one outcome occurring k times in n independent trials is P1E2 = n!k!1n - k2!pk11 - p) n-k where p is the probability of the outcome occurring once

  • Center

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

  • Constant of variation

    See Power function.

  • Coordinate(s) of a point

    The number associated with a point on a number line, or the ordered pair associated with a point in the Cartesian coordinate plane, or the ordered triple associated with a point in the Cartesian three-dimensional space

  • Difference of complex numbers

    (a + bi) - (c + di) = (a - c) + (b - d)i

  • Double-angle identity

    An identity involving a trigonometric function of 2u

  • Fundamental

    Theorem of Algebra A polynomial function of degree has n complex zeros (counting multiplicity).

  • Product of matrices A and B

    The matrix in which each entry is obtained by multiplying the entries of a row of A by the corresponding entries of a column of B and then adding

  • Quotient of complex numbers

    a + bi c + di = ac + bd c2 + d2 + bc - ad c2 + d2 i

  • Reciprocal identity

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

  • 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.

  • Sample standard deviation

    The standard deviation computed using only a sample of the entire population.

  • Sample survey

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

  • Unit circle

    A circle with radius 1 centered at the origin.

  • Upper bound for ƒ

    Any number B for which ƒ(x) ? B for all x in the domain of ƒ.
