Key Calculus Terms and definitions covered in this textbook
• Annual percentage yield (APY)

The rate that would give the same return if interest were computed just once a year

• Arc length formula

The length of an arc in a circle of radius r intercepted by a central angle of u radians is s = r u.

• Coefficient

The real number multiplied by the variable(s) in a polynomial term

• Factor

In algebra, a quantity being multiplied in a product. In statistics, a potential explanatory variable under study in an experiment, .

• Factored form

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

• First octant

The points (x, y, z) in space with x > 0 y > 0, and z > 0.

• First-degree equation in x , y, and z

An equation that can be written in the form.

• Graph of a polar equation

The set of all points in the polar coordinate system corresponding to the ordered pairs (r,?) that are solutions of the polar equation.

• Initial side of an angle

See Angle.

• Minor axis

The perpendicular bisector of the major axis of an ellipse with endpoints on the ellipse.

• One-to-one function

A function in which each element of the range corresponds to exactly one element in the domain

• PH

The measure of acidity

• Power-reducing identity

A trigonometric identity that reduces the power to which the trigonometric functions are raised.

• Quotient of complex numbers

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

• Randomization

The principle of experimental design that makes it possible to use the laws of probability when making inferences.

• Simple harmonic motion

Motion described by d = a sin wt or d = a cos wt

• Sinusoid

A function that can be written in the form f(x) = a sin (b (x - h)) + k or f(x) = a cos (b(x - h)) + k. The number a is the amplitude, and the number h is the phase shift.

• Sum of complex numbers

(a + bi) + (c + di) = (a + c) + (b + d)i

• Transverse axis

The line segment whose endpoints are the vertices of a hyperbola.

• Vertical translation

A shift of a graph up or down.
