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

An interval that has finite length (does not extend to ? or -?)

• Compound interest

Interest that becomes part of the investment

• Derivative of ƒ

The function defined by ƒ'(x) = limh:0ƒ(x + h) - ƒ(x)h for all of x where the limit exists

• Derivative of ƒ at x a

ƒ'(a) = lim x:a ƒ(x) - ƒ(a) x - a provided the limit exists

• Explanatory variable

A variable that affects a response variable.

• Five-number summary

The minimum, first quartile, median, third quartile, and maximum of a data set.

• Intermediate Value Theorem

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

• Inverse relation (of the relation R)

A relation that consists of all ordered pairs b, a for which a, b belongs to R.

• Irrational zeros

Zeros of a function that are irrational numbers.

• Median (of a data set)

The middle number (or the mean of the two middle numbers) if the data are listed in order.

• Parabola

The graph of a quadratic function, or the set of points in a plane that are equidistant from a fixed point (the focus) and a fixed line (the directrix).

• Partial fraction decomposition

See Partial fractions.

• Polar equation

An equation in r and ?.

• Power regression

A procedure for fitting a curve y = a . x b to a set of data.

• 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).

• Terminal side of an angle

See Angle.

• Venn diagram

A visualization of the relationships among events within a sample space.

• x-intercept

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

• yz-plane

The points (0, y, z) in Cartesian space.
