Key Calculus Terms and definitions covered in this textbook
  • Angle

    Union of two rays with a common endpoint (the vertex). The beginning ray (the initial side) can be rotated about its endpoint to obtain the final position (the terminal side)

  • artesian coordinate system

    An association between the points in a plane and ordered pairs of real numbers; or an association between the points in three-dimensional space and ordered triples of real numbers

  • Base

    See Exponential function, Logarithmic function, nth power of a.

  • Cone

    See Right circular cone.

  • Convenience sample

    A sample that sacrifices randomness for convenience

  • Damping factor

    The factor Ae-a in an equation such as y = Ae-at cos bt

  • Degree of a polynomial (function)

    The largest exponent on the variable in any of the terms of the polynomial (function)

  • Division algorithm for polynomials

    Given ƒ(x), d(x) ? 0 there are unique polynomials q1x (quotient) and r1x(remainder) ƒ1x2 = d1x2q1x2 + r1x2 with with either r1x2 = 0 or degree of r(x) 6 degree of d1x2

  • Graph of a polar equation

    The set of all points in the polar coordinate system corresponding to the ordered pairs (r,?) that are solutions of the polar equation.

  • Inverse cotangent function

    The function y = cot-1 x

  • Inverse variation

    See Power function.

  • Law of sines

    sin A a = sin B b = sin C c

  • Lower bound for real zeros

    A number c is a lower bound for the set of real zeros of ƒ if ƒ(x) Z 0 whenever x < c

  • Natural logarithmic function

    The inverse of the exponential function y = ex, denoted by y = ln x.

  • Quantitative variable

    A variable (in statistics) that takes on numerical values for a characteristic being measured.

  • Reference triangle

    For an angle ? in standard position, a reference triangle is a triangle formed by the terminal side of angle ?, the x-axis, and a perpendicular dropped from a point on the terminal side to the x-axis. The angle in a reference triangle at the origin is the reference angle

  • Sinusoidal regression

    A procedure for fitting a curve y = a sin (bx + c) + d to a set of data

  • Terminal point

    See Arrow.

  • Terms of a sequence

    The range elements of a sequence.

  • xy-plane

    The points x, y, 0 in Cartesian space.
