Key Calculus Terms and definitions covered in this textbook
  • Argument of a complex number

    The argument of a + bi is the direction angle of the vector {a,b}.

  • Common logarithm

    A logarithm with base 10.

  • Complex conjugates

    Complex numbers a + bi and a - bi

  • Component form of a vector

    If a vector’s representative in standard position has a terminal point (a,b) (or (a, b, c)) , then (a,b) (or (a, b, c)) is the component form of the vector, and a and b are the horizontal and vertical components of the vector (or a, b, and c are the x-, y-, and z-components of the vector, respectively)

  • Constraints

    See Linear programming problem.

  • End behavior

    The behavior of a graph of a function as.

  • Endpoint of an interval

    A real number that represents one “end” of an interval.

  • equation of a hyperbola

    (x - h)2 a2 - (y - k)2 b2 = 1 or (y - k)2 a2 - (x - h)2 b2 = 1

  • Equivalent arrows

    Arrows that have the same magnitude and direction.

  • Finite series

    Sum of a finite number of terms.

  • First quartile

    See Quartile.

  • Instantaneous velocity

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

  • Midpoint (in a coordinate plane)

    For the line segment with endpoints (a,b) and (c,d), (aa + c2 ,b + d2)

  • Numerical model

    A model determined by analyzing numbers or data in order to gain insight into a phenomenon, p. 64.

  • 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

  • Removable discontinuity at x = a

    lim x:a- ƒ(x) = limx:a+ ƒ(x) but either the common limit is not equal ƒ(a) to ƒ(a) or is not defined

  • Residual

    The difference y1 - (ax 1 + b), where (x1, y1)is a point in a scatter plot and y = ax + b is a line that fits the set of data.

  • Secant

    The function y = sec x.

  • Whole numbers

    The numbers 0, 1, 2, 3, ... .

  • y-intercept

    A point that lies on both the graph and the y-axis.
