Key Calculus Terms and definitions covered in this textbook
• Absolute value of a real number

Denoted by |a|, represents the number a or the positive number -a if a < 0.

If u = v and w = z , then u + w = v + z

• Causation

A relationship between two variables in which the values of the response variable are directly affected by the values of the explanatory variable

• Coterminal angles

Two angles having the same initial side and the same terminal side

• Dependent event

An event whose probability depends on another event already occurring

• Explanatory variable

A variable that affects a response variable.

• Fundamental

Theorem of Algebra A polynomial function of degree has n complex zeros (counting multiplicity).

• Line of travel

The path along which an object travels

• Multiplication property of equality

If u = v and w = z, then uw = vz

• Ordered set

A set is ordered if it is possible to compare any two elements and say that one element is “less than” or “greater than” the other.

• Polynomial in x

An expression that can be written in the form an x n + an-1x n-1 + Á + a1x + a0, where n is a nonnegative integer, the coefficients are real numbers, and an ? 0. The degree of the polynomial is n, the leading coefficient is an, the leading term is anxn, and the constant term is a0. (The number 0 is the zero polynomial)

• Pythagorean

Theorem In a right triangle with sides a and b and hypotenuse c, c2 = a2 + b2

• Rational function

Function of the form ƒ(x)/g(x) where ƒ(x) and g(x) are polynomials and g(x) is not the zero polynomial.

• Reciprocal of a real number

See Multiplicative inverse of a real number.

• Sequence of partial sums

The sequence {Sn} , where Sn is the nth partial sum of the series, that is, the sum of the first n terms of the series.

• Sinusoidal regression

A procedure for fitting a curve y = a sin (bx + c) + d to a set of data

• Standard representation of a vector

A representative arrow with its initial point at the origin

• Symmetric property of equality

If a = b, then b = a

• Terminal point

See Arrow.

• x-intercept

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