Key Calculus Terms and definitions covered in this textbook
• Base

See Exponential function, Logarithmic function, nth power of a.

• Binomial

A polynomial with exactly two terms

• Compounded monthly

See Compounded k times per year.

• Eccentricity

A nonnegative number that specifies how off-center the focus of a conic is

• Equivalent equations (inequalities)

Equations (inequalities) that have the same solutions.

• Leaf

The final digit of a number in a stemplot.

• Left-hand limit of f at x a

The limit of ƒ as x approaches a from the left.

• Limit

limx:aƒ1x2 = L means that ƒ(x) gets arbitrarily close to L as x gets arbitrarily close (but not equal) to a

• Logarithmic form

An equation written with logarithms instead of exponents

• Mode of a data set

The category or number that occurs most frequently in the set.

• Negative association

A relationship between two variables in which higher values of one variable are generally associated with lower values of the other variable.

• Open interval

An interval that does not include its endpoints.

• Origin

The number zero on a number line, or the point where the x- and y-axes cross in the Cartesian coordinate system, or the point where the x-, y-, and z-axes cross in Cartesian three-dimensional space

• Parallelogram representation of vector addition

Geometric representation of vector addition using the parallelogram determined by the position vectors.

• 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.

• Permutation

• Polar axis

See Polar coordinate system.

• Power-reducing identity

A trigonometric identity that reduces the power to which the trigonometric functions are raised.
