Key Calculus Terms and definitions covered in this textbook
  • Additive identity for the complex numbers

    0 + 0i is the complex number zero

  • 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)

  • Binomial

    A polynomial with exactly two terms

  • Central angle

    An angle whose vertex is the center of a circle

  • Coefficient of determination

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

  • Constraints

    See Linear programming problem.

  • Direction of an arrow

    The angle the arrow makes with the positive x-axis

  • Elementary row operations

    The following three row operations: Multiply all elements of a row by a nonzero constant; interchange two rows; and add a multiple of one row to another row

  • Horizontal Line Test

    A test for determining whether the inverse of a relation is a function.

  • Inductive step

    See Mathematical induction.

  • Measure of spread

    A measure that tells how widely distributed data are.

  • Modified boxplot

    A boxplot with the outliers removed.

  • nth root of a complex number z

    A complex number v such that vn = z

  • Opens upward or downward

    A parabola y = ax 2 + bx + c opens upward if a > 0 and opens downward if a < 0.

  • Partial sums

    See Sequence of partial sums.

  • Perpendicular lines

    Two lines that are at right angles to each other

  • Radicand

    See Radical.

  • Randomization

    The principle of experimental design that makes it possible to use the laws of probability when making inferences.

  • Standard position (angle)

    An angle positioned on a rectangular coordinate system with its vertex at the origin and its initial side on the positive x-axis

  • Sum identity

    An identity involving a trigonometric function of u + v
