Key Calculus Terms and definitions covered in this textbook
• Bounded below

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

• Combinations of n objects taken r at a time

There are nCr = n! r!1n - r2! such combinations,

• Compound interest

Interest that becomes part of the investment

• Damping factor

The factor Ae-a in an equation such as y = Ae-at cos bt

• Deductive reasoning

The process of utilizing general information to prove a specific hypothesis

• Degree of a polynomial (function)

The largest exponent on the variable in any of the terms of the polynomial (function)

• Horizontal Line Test

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

• Major axis

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

• Natural exponential function

The function ƒ1x2 = ex.

• Normal distribution

A distribution of data shaped like the normal curve.

• Quotient of complex numbers

a + bi c + di = ac + bd c2 + d2 + bc - ad c2 + d2 i
