Key Calculus Terms and definitions covered in this textbook
  • Addition property of equality

    If u = v and w = z , then u + w = v + z

  • Anchor

    See Mathematical induction.

  • Angular speed

    Speed of rotation, typically measured in radians or revolutions per unit time

  • Binomial

    A polynomial with exactly two terms

  • Complex plane

    A coordinate plane used to represent the complex numbers. The x-axis of the complex plane is called the real axis and the y-axis is the imaginary axis

  • Constraints

    See Linear programming problem.

  • Deductive reasoning

    The process of utilizing general information to prove a specific hypothesis

  • Degree

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

  • Empty set

    A set with no elements

  • Equivalent arrows

    Arrows that have the same magnitude and direction.

  • Equivalent equations (inequalities)

    Equations (inequalities) that have the same solutions.

  • 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.

  • Intermediate Value Theorem

    If ƒ is a polynomial function and a < b , then ƒ assumes every value between ƒ(a) and ƒ(b).

  • Multiplication principle of counting

    A principle used to find the number of ways an event can occur.

  • Positive linear correlation

    See Linear correlation.

  • Quadratic regression

    A procedure for fitting a quadratic function to a set of data.

  • Reflection through the origin

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

  • Solve graphically

    Use a graphical method, including use of a hand sketch or use of a grapher. When appropriate, the approximate solution should be confirmed algebraically

  • Symmetric property of equality

    If a = b, then b = a

  • 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>.
