Key Calculus Terms and definitions covered in this textbook
• Average velocity

The change in position divided by the change in time.

• Cycloid

The graph of the parametric equations

• Endpoint of an interval

A real number that represents one “end” of an interval.

• Exponential function

A function of the form ƒ(x) = a ? bx,where ?0, b > 0 b ?1

• Factored form

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

• Focal width of a parabola

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

• Integrable over [a, b] Lba

ƒ1x2 dx exists.

• Inverse relation (of the relation R)

A relation that consists of all ordered pairs b, a for which a, b belongs to R.

• Law of sines

sin A a = sin B b = sin C c

• Mapping

A function viewed as a mapping of the elements of the domain onto the elements of the range

• Negative angle

Angle generated by clockwise rotation.

• Order of an m x n matrix

The order of an m x n matrix is m x n.

• Parametric curve

The graph of parametric equations.

The distance from a point on a circle (or a sphere) to the center of the circle (or the sphere).

• Reflection through the origin

x, y and (-x,-y) are reflections of each other through the origin.

• Relevant domain

The portion of the domain applicable to the situation being modeled.

• 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

One-half of the sum of the lengths of the sides of a triangle.

• xz-plane

The points x, 0, z in Cartesian space.

• Zoom out
