Key Calculus Terms and definitions covered in this textbook
• Compounded k times per year

Interest compounded using the formula A = Pa1 + rkbkt where k = 1 is compounded annually, k = 4 is compounded quarterly k = 12 is compounded monthly, etc.

• Cubic

A degree 3 polynomial function

• Difference of two vectors

<u1, u2> - <v1, v2> = <u1 - v1, u2 - v2> or <u1, u2, u3> - <v1, v2, v3> = <u1 - v1, u2 - v2, u3 - v3>

• Equivalent vectors

Vectors with the same magnitude and direction.

• Exponent

See nth power of a.

• Higher-degree polynomial function

A polynomial function whose degree is ? 3

• Index

• Inverse tangent function

The function y = tan-1 x

• Logarithmic re-expression of data

Transformation of a data set involving the natural logarithm: exponential regression, natural logarithmic regression, power regression

• Median (of a data set)

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

• 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)

• Outliers

Data items more than 1.5 times the IQR below the first quartile or above the third quartile.

• Parametric equations for a line in space

The line through P0(x 0, y0, z 0) in the direction of the nonzero vector v = <a, b, c> has parametric equations x = x 0 + at, y = y 0 + bt, z = z0 + ct.

A function that can be written in the form ƒ(x) = ax 2 + bx + c, where a, b, and c are real numbers, and a ? 0.

• Sequence

See Finite sequence, Infinite sequence.

• Solve a system

To find all solutions of a system.

A graph in which (x, -y) is on the graph whenever (x, y) is; or a graph in which (r, -?) or (-r, ?, -?) is on the graph whenever (r, ?) is

• Tangent line of ƒ at x = a

The line through (a, ƒ(a)) with slope ƒ'(a) provided ƒ'(a) exists.

• Transpose of a matrix

The matrix AT obtained by interchanging the rows and columns of A.

• Vertical translation

A shift of a graph up or down.
