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}.

  • Coefficient

    The real number multiplied by the variable(s) in a polynomial term

  • 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

  • Coterminal angles

    Two angles having the same initial side and the same terminal side

  • Difference of functions

    (ƒ - g)(x) = ƒ(x) - g(x)

  • Frequency (in statistics)

    The number of individuals or observations with a certain characteristic.

  • Intercept

    Point where a curve crosses the x-, y-, or z-axis in a graph.

  • Leibniz notation

    The notation dy/dx for the derivative of ƒ.

  • Modified boxplot

    A boxplot with the outliers removed.

  • nth root of unity

    A complex number v such that vn = 1

  • Number line graph of a linear inequality

    The graph of the solutions of a linear inequality (in x) on a number line

  • Quartile

    The first quartile is the median of the lower half of a set of data, the second quartile is the median, and the third quartile is the median of the upper half of the data.

  • Range screen

    See Viewing window.

  • 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.

  • 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

  • Statute mile

    5280 feet.

  • Variation

    See Power function.

  • Vector equation for a line in space

    The line through P0(x 0, y0, z0) in the direction of the nonzero vector V = <a, b, c> has vector equation r = r0 + tv , where r = <x,y,z>.

  • Vertices of a hyperbola

    The points where a hyperbola intersects the line containing its foci.

  • Weighted mean

    A mean calculated in such a way that some elements of the data set have higher weights (that is, are counted more strongly in determining the mean) than others.
