Key Calculus Terms and definitions covered in this textbook
  • Absolute value of a real number

    Denoted by |a|, represents the number a or the positive number -a if a < 0.

  • 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

  • Boxplot (or box-and-whisker plot)

    A graph that displays a five-number summary

  • Circular functions

    Trigonometric functions when applied to real numbers are circular functions

  • Combinatorics

    A branch of mathematics related to determining the number of elements of a set or the number of ways objects can be arranged or combined

  • Degree

    Unit of measurement (represented by the symbol ) for angles or arcs, equal to 1/360 of a complete revolution

  • Expanded form of a series

    A series written explicitly as a sum of terms (not in summation notation).

  • Geometric sequence

    A sequence {an}in which an = an-1.r for every positive integer n ? 2. The nonzero number r is called the common ratio.

  • Imaginary part of a complex number

    See Complex number.

  • Interval

    Connected subset of the real number line with at least two points, p. 4.

  • Line graph

    A graph of data in which consecutive data points are connected by line segments

  • Midpoint (in a coordinate plane)

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

  • Multiplicative identity for matrices

    See Identity matrix

  • Opens upward or downward

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

  • Parametric equations for a line in space

    The line through P0(x 0, y0, z 0) in the direction of the nonzero vector v = <a, b, c> has parametric equations x = x 0 + at, y = y 0 + bt, z = z0 + ct.

  • Polar distance formula

    The distance between the points with polar coordinates (r1, ?1 ) and (r2, ?2 ) = 2r 12 + r 22 - 2r1r2 cos 1?1 - ?22

  • Reflection through the origin

    x, y and (-x,-y) are reflections of each other through the origin.

  • Regression model

    An equation found by regression and which can be used to predict unknown values.

  • Sum of an infinite geometric series

    Sn = a 1 - r , |r| 6 1

  • Transitive property

    If a = b and b = c , then a = c. Similar properties hold for the inequality symbols <, >, ?, ?.
