Key Calculus Terms and definitions covered in this textbook
• Axis of symmetry

See Line of symmetry.

• Division

a b = aa 1 b b, b Z 0

• Dot product

The number found when the corresponding components of two vectors are multiplied and then summed

• equation of a quadratic function

ƒ(x) = ax 2 + bx + c(a ? 0)

• Half-angle identity

Identity involving a trigonometric function of u/2.

• Leaf

The final digit of a number in a stemplot.

• Line of symmetry

A line over which a graph is the mirror image of itself

• nth power of a

The number with n factors of a , where n is the exponent and a is the base.

• Observational study

A process for gathering data from a subset of a population through current or past observations. This differs from an experiment in that no treatment is imposed.

• Open interval

An interval that does not include its endpoints.

• Parallel lines

Two lines that are both vertical or have equal slopes.

An equation that can be written in the form ax 2 + bx + c = 01a ? 02

The formula x = -b 2b2 - 4ac2a used to solve ax 2 + bx + c = 0.

• Reflexive property of equality

a = a

• Removable discontinuity at x = a

lim x:a- ƒ(x) = limx:a+ ƒ(x) but either the common limit is not equal ƒ(a) to ƒ(a) or is not defined

• Row echelon form

A matrix in which rows consisting of all 0’s occur only at the bottom of the matrix, the first nonzero entry in any row with nonzero entries is 1, and the leading 1’s move to the right as we move down the rows.

• Subtraction

a - b = a + (-b)

• Vertical line test

A test for determining whether a graph is a function.

• Wrapping function

The function that associates points on the unit circle with points on the real number line

• y-intercept

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