Key Calculus Terms and definitions covered in this textbook
  • Algebraic model

    An equation that relates variable quantities associated with phenomena being studied

  • Aphelion

    The farthest point from the Sun in a planet’s orbit

  • Axis of symmetry

    See Line of symmetry.

  • 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

  • Divergence

    A sequence or series diverges if it does not converge

  • Equivalent equations (inequalities)

    Equations (inequalities) that have the same solutions.

  • Identity function

    The function ƒ(x) = x.

  • Infinite sequence

    A function whose domain is the set of all natural numbers.

  • Integrable over [a, b] Lba

    ƒ1x2 dx exists.

  • Left-hand limit of f at x a

    The limit of ƒ as x approaches a from the left.

  • Opens upward or downward

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

  • Partial fractions

    The process of expanding a fraction into a sum of fractions. The sum is called the partial fraction decomposition of the original fraction.

  • Phase shift

    See Sinusoid.

  • Quadratic function

    A function that can be written in the form ƒ(x) = ax 2 + bx + c, where a, b, and c are real numbers, and a ? 0.

  • Reference triangle

    For an angle ? in standard position, a reference triangle is a triangle formed by the terminal side of angle ?, the x-axis, and a perpendicular dropped from a point on the terminal side to the x-axis. The angle in a reference triangle at the origin is the reference angle

  • Sum of a finite geometric series

    Sn = a111 - r n 2 1 - r

  • Sum of functions

    (ƒ + g)(x) = ƒ(x) + g(x)

  • Trigonometric form of a complex number

    r(cos ? + i sin ?)

  • Velocity

    A vector that specifies the motion of an object in terms of its speed and direction.

  • Zero factor property

    If ab = 0 , then either a = 0 or b = 0.
