Key Calculus Terms and definitions covered in this textbook
  • 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

  • Dependent event

    An event whose probability depends on another event already occurring

  • equation of a parabola

    (x - h)2 = 4p(y - k) or (y - k)2 = 4p(x - h)

  • Fibonacci numbers

    The terms of the Fibonacci sequence.

  • Focus, foci

    See Ellipse, Hyperbola, Parabola.

  • Gaussian elimination

    A method of solving a system of n linear equations in n unknowns.

  • 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.

  • Instantaneous velocity

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

  • Interval

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

  • Multiplication principle of counting

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

  • Parametric curve

    The graph of parametric equations.

  • Power function

    A function of the form ƒ(x) = k . x a, where k and a are nonzero constants. k is the constant of variation and a is the power.

  • Random numbers

    Numbers that can be used by researchers to simulate randomness in scientific studies (they are usually obtained from lengthy tables of decimal digits that have been generated by verifiably random natural phenomena).

  • Solve a system

    To find all solutions of a system.

  • Transverse axis

    The line segment whose endpoints are the vertices of a hyperbola.

  • Union of two sets A and B

    The set of all elements that belong to A or B or both.

  • Vertex of an angle

    See Angle.

  • Wrapping function

    The function that associates points on the unit circle with points on the real number line

  • x-axis

    Usually the horizontal coordinate line in a Cartesian coordinate system with positive direction to the right,.

  • x-coordinate

    The directed distance from the y-axis yz-plane to a point in a plane (space), or the first number in an ordered pair (triple), pp. 12, 629.
