Key Calculus Terms and definitions covered in this textbook
  • Angle of elevation

    The acute angle formed by the line of sight (upward) and the horizontal

  • Bounded below

    A function is bounded below if there is a number b such that b ? ƒ(x) for all x in the domain of f.

  • Complex fraction

    See Compound fraction.

  • Control

    The principle of experimental design that makes it possible to rule out other factors when making inferences about a particular explanatory variable

  • Deductive reasoning

    The process of utilizing general information to prove a specific hypothesis

  • Difference identity

    An identity involving a trigonometric function of u - v

  • Horizontal translation

    A shift of a graph to the left or right.

  • Inverse function

    The inverse relation of a one-to-one function.

  • Law of sines

    sin A a = sin B b = sin C c

  • Lemniscate

    A graph of a polar equation of the form r2 = a2 sin 2u or r 2 = a2 cos 2u.

  • Limit

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

  • Midpoint (in Cartesian space)

    For the line segment with endpoints (x 1, y1, z 1) and (x2, y2, z2), ax 1 + x 22 ,y1 + y22 ,z 1 + z 22 b

  • Multiplication property of equality

    If u = v and w = z, then uw = vz

  • Product of complex numbers

    (a + bi)(c + di) = (ac - bd) + (ad + bc)i

  • Radius

    The distance from a point on a circle (or a sphere) to the center of the circle (or the sphere).

  • Repeated zeros

    Zeros of multiplicity ? 2 (see Multiplicity).

  • Solve graphically

    Use a graphical method, including use of a hand sketch or use of a grapher. When appropriate, the approximate solution should be confirmed algebraically

  • Spiral of Archimedes

    The graph of the polar curve.

  • Symmetric property of equality

    If a = b, then b = a

  • Xscl

    The scale of the tick marks on the x-axis in a viewing window.
