Key Calculus Terms and definitions covered in this textbook
• Additive inverse of a complex number

The opposite of a + bi, or -a - bi

• Confounding variable

A third variable that affects either of two variables being studied, making inferences about causation unreliable

• Continuous function

A function that is continuous on its entire domain

• Explicitly defined sequence

A sequence in which the kth term is given as a function of k.

• Exponential form

An equation written with exponents instead of logarithms.

• Exponential regression

A procedure for fitting an exponential function to a set of data.

• Focal width of a parabola

The length of the chord through the focus and perpendicular to the axis.

• Infinite sequence

A function whose domain is the set of all natural numbers.

• Irreducible quadratic over the reals

A quadratic polynomial with real coefficients that cannot be factored using real coefficients.

• Local maximum

A value ƒ(c) is a local maximum of ƒ if there is an open interval I containing c such that ƒ(x) < ƒ(c) for all values of x in I

• Multiplication principle of probability

If A and B are independent events, then P(A and B) = P(A) # P(B). If Adepends on B, then P(A and B) = P(A|B) # P(B)

• Multiplicative inverse of a matrix

See Inverse of a matrix

• Nappe

See Right circular cone.

• nth root

See Principal nth root

• Outcomes

The various possible results of an experiment.

The measure of an angle in radians, or, for a central angle, the ratio of the length of the intercepted arc tothe radius of the circle.

• Real axis

See Complex plane.

• Riemann sum

A sum where the interval is divided into n subintervals of equal length and is in the ith subinterval.

• Sequence

See Finite sequence, Infinite sequence.

• Vertices of a hyperbola

The points where a hyperbola intersects the line containing its foci.
