Key Calculus Terms and definitions covered in this textbook
  • Angle of elevation

    The acute angle formed by the line of sight (upward) and the horizontal

  • Annuity

    A sequence of equal periodic payments.

  • 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

  • Constant function (on an interval)

    ƒ(x 1) = ƒ(x 2) x for any x1 and x2 (in the interval)

  • Convergence of a sequence

    A sequence {an} converges to a if limn: q an = a

  • Cubic

    A degree 3 polynomial function

  • Derivative of ƒ at x a

    ƒ'(a) = lim x:a ƒ(x) - ƒ(a) x - a provided the limit exists

  • Fibonacci sequence

    The sequence 1, 1, 2, 3, 5, 8, 13, . . ..

  • Horizontal Line Test

    A test for determining whether the inverse of a relation is a function.

  • Inverse cosecant function

    The function y = csc-1 x

  • Inverse tangent function

    The function y = tan-1 x

  • Irrational numbers

    Real numbers that are not rational, p. 2.

  • Irrational zeros

    Zeros of a function that are irrational numbers.

  • Linear correlation

    A scatter plot with points clustered along a line. Correlation is positive if the slope is positive and negative if the slope is negative

  • Multiplicative inverse of a complex number

    The reciprocal of a + bi, or 1 a + bi = a a2 + b2- ba2 + b2 i

  • Natural logarithmic function

    The inverse of the exponential function y = ex, denoted by y = ln x.

  • Outcomes

    The various possible results of an experiment.

  • Pole

    See Polar coordinate system.

  • Projectile motion

    The movement of an object that is subject only to the force of gravity

  • Vertices of an ellipse

    The points where the ellipse intersects its focal axis.
