Key Calculus Terms and definitions covered in this textbook
  • Aphelion

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

  • Arccotangent function

    See Inverse cotangent function.

  • Branches

    The two separate curves that make up a hyperbola

  • Compound interest

    Interest that becomes part of the investment

  • Difference of complex numbers

    (a + bi) - (c + di) = (a - c) + (b - d)i

  • Directrix of a parabola, ellipse, or hyperbola

    A line used to determine the conic

  • Empty set

    A set with no elements

  • Infinite discontinuity at x = a

    limx:a + x a ƒ(x) = q6 or limx:a - ƒ(x) = q.

  • Intermediate Value Theorem

    If ƒ is a polynomial function and a < b , then ƒ assumes every value between ƒ(a) and ƒ(b).

  • Interval notation

    Notation used to specify intervals, pp. 4, 5.

  • Linear equation in x

    An equation that can be written in the form ax + b = 0, where a and b are real numbers and a Z 0

  • Linear regression equation

    Equation of a linear regression line

  • Plane in Cartesian space

    The graph of Ax + By + Cz + D = 0, where A, B, and C are not all zero.

  • Random numbers

    Numbers that can be used by researchers to simulate randomness in scientific studies (they are usually obtained from lengthy tables of decimal digits that have been generated by verifiably random natural phenomena).

  • Reflection across the y-axis

    x, y and (-x,y) are reflections of each other across the y-axis.

  • Richter scale

    A logarithmic scale used in measuring the intensity of an earthquake.

  • Solve algebraically

    Use an algebraic method, including paper and pencil manipulation and obvious mental work, with no calculator or grapher use. When appropriate, the final exact solution may be approximated by a calculator

  • Subtraction

    a - b = a + (-b)

  • Symmetric about the y-axis

    A graph in which (-x, y) is on the graph whenever (x, y) is; or a graph in which (-r, -?) or (r, ?, -?) is on the graph whenever (r, ?) is

  • Trigonometric form of a complex number

    r(cos ? + i sin ?)
