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

    If u < v , then u + w < v + w

  • Amplitude

    See Sinusoid.

  • Bounded above

    A function is bounded above if there is a number B such that ƒ(x) ? B for all x in the domain of ƒ.

  • Coefficient

    The real number multiplied by the variable(s) in a polynomial term

  • Completing the square

    A method of adding a constant to an expression in order to form a perfect square

  • Compound interest

    Interest that becomes part of the investment

  • Equation

    A statement of equality between two expressions.

  • Graph of an equation in x and y

    The set of all points in the coordinate plane corresponding to the pairs x, y that are solutions of the equation.

  • Inverse cotangent function

    The function y = cot-1 x

  • 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.

  • Probability distribution

    The collection of probabilities of outcomes in a sample space assigned by a probability function.

  • Probability function

    A function P that assigns a real number to each outcome O in a sample space satisfying: 0 … P1O2 … 1, P12 = 0, and the sum of the probabilities of all outcomes is 1.

  • Pseudo-random numbers

    Computer-generated numbers that can be used to approximate true randomness in scientific studies. Since they depend on iterative computer algorithms, they are not truly random

  • Radius

    The distance from a point on a circle (or a sphere) to the center of the circle (or the sphere).

  • Random variable

    A function that assigns real-number values to the outcomes in a sample space.

  • Reflection across the x-axis

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

  • Resolving a vector

    Finding the horizontal and vertical components of a vector.

  • Solve a system

    To find all solutions of a system.

  • Statistic

    A number that measures a quantitative variable for a sample from a population.

  • y-intercept

    A point that lies on both the graph and the y-axis.
