Key Calculus Terms and definitions covered in this textbook
• Continuous at x = a

lim x:a x a ƒ(x) = ƒ(a)

• Equivalent arrows

Arrows that have the same magnitude and direction.

• Fitting a line or curve to data

Finding a line or curve that comes close to passing through all the points in a scatter plot.

• Focal width of a parabola

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

• Identity

An equation that is always true throughout its domain.

• Irrational zeros

Zeros of a function that are irrational numbers.

See Polynomial function in x

• Logarithmic re-expression of data

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

• Maximum r-value

The value of |r| at the point on the graph of a polar equation that has the maximum distance from the pole

• Midpoint (on a number line)

For the line segment with endpoints a and b, a + b2

• Opens upward or downward

A parabola y = ax 2 + bx + c opens upward if a > 0 and opens downward if a < 0.

• 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

An angle in standard position whose terminal side lies on an axis.

• Quotient of complex numbers

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

• Right angle

A 90° angle.

• Rigid transformation

A transformation that leaves the basic shape of a graph unchanged.

• Root of an equation

A solution.

• Standard deviation

A measure of how a data set is spread

• Symmetric matrix

A matrix A = [aij] with the property aij = aji for all i and j

• Vertex form for a quadratic function

ƒ(x) = a(x - h)2 + k
