Key Calculus Terms and definitions covered in this textbook
• Algebraic expression

A combination of variables and constants involving addition, subtraction, multiplication, division, powers, and roots

• Common logarithm

A logarithm with base 10.

• Constraints

See Linear programming problem.

• Difference identity

An identity involving a trigonometric function of u - v

• Domain of a function

The set of all input values for a function

• Elementary row operations

The following three row operations: Multiply all elements of a row by a nonzero constant; interchange two rows; and add a multiple of one row to another row

• Exponential form

An equation written with exponents instead of logarithms.

• Factored form

The left side of u(v + w) = uv + uw.

• Graph of an inequality in x and y

The set of all points in the coordinate plane corresponding to the solutions x, y of the inequality.

• Horizontal shrink or stretch

See Shrink, stretch.

• Identity function

The function ƒ(x) = x.

• Logarithmic function with base b

The inverse of the exponential function y = bx, denoted by y = logb x

• Minor axis

The perpendicular bisector of the major axis of an ellipse with endpoints on the ellipse.

• Negative linear correlation

See Linear correlation.

• Partial fraction decomposition

See Partial fractions.

• Pseudo-random numbers

Computer-generated numbers that can be used to approximate true randomness in scientific studies. Since they depend on iterative computer algorithms, they are not truly random

• Quantitative variable

A variable (in statistics) that takes on numerical values for a characteristic being measured.

• Quotient of complex numbers

a + bi c + di = ac + bd c2 + d2 + bc - ad c2 + d2 i

• Remainder theorem

If a polynomial f(x) is divided by x - c , the remainder is ƒ(c)

• Zero vector

The vector <0,0> or <0,0,0>.
