Key Calculus Terms and definitions covered in this textbook
• Arccosine function

See Inverse cosine function.

• Binomial probability

In an experiment with two possible outcomes, the probability of one outcome occurring k times in n independent trials is P1E2 = n!k!1n - k2!pk11 - p) n-k where p is the probability of the outcome occurring once

• Compounded continuously

Interest compounded using the formula A = Pert

• Constant

A letter or symbol that stands for a specific number,

• Course

See Bearing.

• Equilibrium price

See Equilibrium point.

• Equivalent systems of equations

Systems of equations that have the same solution.

• Initial side of an angle

See Angle.

• Linear regression

A procedure for finding the straight line that is the best fit for the data

• Major axis

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

• Octants

The eight regions of space determined by the coordinate planes.

• One-to-one function

A function in which each element of the range corresponds to exactly one element in the domain

• 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.

• Positive angle

Angle generated by a counterclockwise rotation.

• 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.

• Product rule of logarithms

ogb 1RS2 = logb R + logb S, R > 0, S > 0,

• Range of a function

The set of all output values corresponding to elements in the domain.

• RRAM

A Riemann sum approximation of the area under a curve ƒ(x) from x = a to x = b using x1 as the right-hand end point of each subinterval.

• Second-degree equation in two variables

Ax 2 + Bxy + Cy2 + Dx + Ey + F = 0, where A, B, and C are not all zero.

• Weighted mean

A mean calculated in such a way that some elements of the data set have higher weights (that is, are counted more strongly in determining the mean) than others.
