Key Calculus Terms and definitions covered in this textbook
  • Anchor

    See Mathematical induction.

  • Coefficient of determination

    The number r2 or R2 that measures how well a regression curve fits the data

  • Compound interest

    Interest that becomes part of the investment

  • Conjugate axis of a hyperbola

    The line segment of length 2b that is perpendicular to the focal axis and has the center of the hyperbola as its midpoint

  • Difference of two vectors

    <u1, u2> - <v1, v2> = <u1 - v1, u2 - v2> or <u1, u2, u3> - <v1, v2, v3> = <u1 - v1, u2 - v2, u3 - v3>

  • Distributive property

    a(b + c) = ab + ac and related properties

  • Inductive step

    See Mathematical induction.

  • Instantaneous velocity

    The instantaneous rate of change of a position function with respect to time, p. 737.

  • Inverse cosecant function

    The function y = csc-1 x

  • Irrational numbers

    Real numbers that are not rational, p. 2.

  • Length of an arrow

    See Magnitude of an arrow.

  • Linear inequality in x

    An inequality that can be written in the form ax + b < 0 ,ax + b … 0 , ax + b > 0, or ax + b Ú 0, where a and b are real numbers and a Z 0

  • 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

  • Quadratic formula

    The formula x = -b 2b2 - 4ac2a used to solve ax 2 + bx + c = 0.

  • Quadratic function

    A function that can be written in the form ƒ(x) = ax 2 + bx + c, where a, b, and c are real numbers, and a ? 0.

  • Riemann sum

    A sum where the interval is divided into n subintervals of equal length and is in the ith subinterval.

  • Sum of complex numbers

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

  • Synthetic division

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