Key Calculus Terms and definitions covered in this textbook
  • Argument of a complex number

    The argument of a + bi is the direction angle of the vector {a,b}.

  • Basic logistic function

    The function ƒ(x) = 1 / 1 + e-x

  • Divergence

    A sequence or series diverges if it does not converge

  • Half-life

    The amount of time required for half of a radioactive substance to decay.

  • Increasing on an interval

    A function ƒ is increasing on an interval I if, for any two points in I, a positive change in x results in a positive change in.

  • Independent events

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

  • Inverse cosine function

    The function y = cos-1 x

  • Major axis

    The line segment through the foci of an ellipse with endpoints on the ellipse

  • Negative linear correlation

    See Linear correlation.

  • Normal distribution

    A distribution of data shaped like the normal curve.

  • Odd-even identity

    For a basic trigonometric function f, an identity relating f(x) to f(-x).

  • Power rule of logarithms

    logb Rc = c logb R, R 7 0.

  • Pythagorean identities

    sin2 u + cos2 u = 1, 1 + tan2 u = sec2 u, and 1 + cot2 u = csc2 u

  • Quadrant

    Any one of the four parts into which a plane is divided by the perpendicular coordinate axes.

  • Real number

    Any number that can be written as a decimal.

  • Solve graphically

    Use a graphical method, including use of a hand sketch or use of a grapher. When appropriate, the approximate solution should be confirmed algebraically

  • Standard representation of a vector

    A representative arrow with its initial point at the origin

  • Terminal side of an angle

    See Angle.

  • Upper bound test for real zeros

    A test for finding an upper bound for the real zeros of a polynomial.

  • Variance

    The square of the standard deviation.
