Key Calculus Terms and definitions covered in this textbook
  • Annual percentage yield (APY)

    The rate that would give the same return if interest were computed just once a year

  • Arc length formula

    The length of an arc in a circle of radius r intercepted by a central angle of u radians is s = r u.

  • Coefficient

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

  • Factor

    In algebra, a quantity being multiplied in a product. In statistics, a potential explanatory variable under study in an experiment, .

  • Factored form

    The left side of u(v + w) = uv + uw.

  • First octant

    The points (x, y, z) in space with x > 0 y > 0, and z > 0.

  • First-degree equation in x , y, and z

    An equation that can be written in the form.

  • 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.

  • Initial side of an angle

    See Angle.

  • Minor axis

    The perpendicular bisector of the major axis of an ellipse with endpoints on the ellipse.

  • One-to-one function

    A function in which each element of the range corresponds to exactly one element in the domain

  • PH

    The measure of acidity

  • Power-reducing identity

    A trigonometric identity that reduces the power to which the trigonometric functions are raised.

  • Quotient of complex numbers

    a + bi c + di = ac + bd c2 + d2 + bc - ad c2 + d2 i

  • Randomization

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

  • Simple harmonic motion

    Motion described by d = a sin wt or d = a cos wt

  • Sinusoid

    A function that can be written in the form f(x) = a sin (b (x - h)) + k or f(x) = a cos (b(x - h)) + k. The number a is the amplitude, and the number h is the phase shift.

  • Sum of complex numbers

    (a + bi) + (c + di) = (a + c) + (b + d)i

  • Transverse axis

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

  • Vertical translation

    A shift of a graph up or down.
