Key Calculus Terms and definitions covered in this textbook
  • Average rate of change of ƒ over [a, b]

    The number ƒ(b) - ƒ(a) b - a, provided a ? b.

  • Binomial probability

    In an experiment with two possible outcomes, the probability of one outcome occurring k times in n independent trials is P1E2 = n!k!1n - k2!pk11 - p) n-k where p is the probability of the outcome occurring once

  • Double-angle identity

    An identity involving a trigonometric function of 2u

  • Expanded form

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

  • Explanatory variable

    A variable that affects a response variable.

  • Exponential regression

    A procedure for fitting an exponential function to a set of data.

  • Independent events

    Events A and B such that P(A and B) = P(A)P(B)

  • Intercepted arc

    Arc of a circle between the initial side and terminal side of a central angle.

  • Law of sines

    sin A a = sin B b = sin C c

  • Leaf

  • Nonsingular matrix

    A square matrix with nonzero determinant

  • One-to-one function

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

  • Opens upward or downward

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

  • Parameter

    See Parametric equations.

  • Probability of an event in a finite sample space of equally likely outcomes

    The number of outcomes in the event divided by the number of outcomes in the sample space.

  • Quotient identities

    tan ?= sin ?cos ?and cot ?= cos ? sin ?

  • Standard form: equation of a circle

    (x - h)2 + (y - k2) = r 2

  • Standard unit vectors

    In the plane i = <1, 0> and j = <0,1>; in space i = <1,0,0>, j = <0,1,0> k = <0,0,1>

  • Statistic

    A number that measures a quantitative variable for a sample from a population.
