Key Calculus Terms and definitions covered in this textbook
• Coterminal angles

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

• Ellipsoid of revolution

A surface generated by rotating an ellipse about its major axis

• Exponential decay function

Decay modeled by ƒ(x) = a ? bx, a > 0 with 0 < b < 1.

• Graph of parametric equations

The set of all points in the coordinate plane corresponding to the ordered pairs determined by the parametric equations.

• Horizontal Line Test

A test for determining whether the inverse of a relation is a function.

• Infinite discontinuity at x = a

limx:a + x a ƒ(x) = q6 or limx:a - ƒ(x) = q.

• Law of cosines

a2 = b2 + c2 - 2bc cos A, b2 = a2 + c2 - 2ac cos B, c2 = a2 + b2 - 2ab cos C

• Local maximum

A value ƒ(c) is a local maximum of ƒ if there is an open interval I containing c such that ƒ(x) < ƒ(c) for all values of x in I

• Magnitude of a real number

See Absolute value of a real number

• nth power of a

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

• Numerical derivative of ƒ at a

NDER f(a) = ƒ1a + 0.0012 - ƒ1a - 0.00120.002

• 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.

• Opens upward or downward

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

• Parallel lines

Two lines that are both vertical or have equal slopes.

• Secant

The function y = sec x.

A graph in which (-x, y) is on the graph whenever (x, y) is; or a graph in which (-r, -?) or (r, ?, -?) is on the graph whenever (r, ?) is

• System

A set of equations or inequalities.

• Vertex form for a quadratic function

ƒ(x) = a(x - h)2 + k

• Vertical stretch or shrink

See Stretch, Shrink.
