Key Calculus Terms and definitions covered in this textbook
  • Addition property of equality

    If u = v and w = z , then u + w = v + z

  • 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.

  • artesian coordinate system

    An association between the points in a plane and ordered pairs of real numbers; or an association between the points in three-dimensional space and ordered triples of real numbers

  • Associative properties

    a + (b + c) = (a + b) + c, a(bc) = (ab)c.

  • Common difference

    See Arithmetic sequence.

  • Complex conjugates

    Complex numbers a + bi and a - bi

  • Compounded monthly

    See Compounded k times per year.

  • Ellipse

    The set of all points in the plane such that the sum of the distances from a pair of fixed points (the foci) is a constant

  • Equation

    A statement of equality between two expressions.

  • Event

    A subset of a sample space.

  • Leaf

    The final digit of a number in a stemplot.

  • Major axis

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

  • Point-slope form (of a line)

    y - y1 = m1x - x 12.

  • Product of matrices A and B

    The matrix in which each entry is obtained by multiplying the entries of a row of A by the corresponding entries of a column of B and then adding

  • Quartile

    The first quartile is the median of the lower half of a set of data, the second quartile is the median, and the third quartile is the median of the upper half of the data.

  • Rectangular coordinate system

    See Cartesian coordinate system.

  • Riemann sum

    A sum where the interval is divided into n subintervals of equal length and is in the ith subinterval.

  • Standard form of a polynomial function

    ƒ(x) = an x n + an-1x n-1 + Á + a1x + a0

  • Stretch of factor c

    A transformation of a graph obtained by multiplying all the x-coordinates (horizontal stretch) by the constant 1/c, or all of the y-coordinates (vertical stretch) of the points by a constant c, c, > 1.

  • Vertex of an angle

    See Angle.
