Key Calculus Terms and definitions covered in this textbook
• Binomial

A polynomial with exactly two terms

• Blind experiment

An experiment in which subjects do not know if they have been given an active treatment or a placebo

• Central angle

An angle whose vertex is the center of a circle

• Complex plane

A coordinate plane used to represent the complex numbers. The x-axis of the complex plane is called the real axis and the y-axis is the imaginary axis

• Conditional probability

The probability of an event A given that an event B has already occurred

• Constant term

See Polynomial function

• Double-angle identity

An identity involving a trigonometric function of 2u

• Frequency distribution

See Frequency table.

• Imaginary axis

See Complex plane.

• LRAM

A Riemann sum approximation of the area under a curve ƒ(x) from x = a to x = b using x1 as the left-hand endpoint of each subinterval

• Modulus

See Absolute value of a complex number.

• nth root of unity

A complex number v such that vn = 1

• Point-slope form (of a line)

y - y1 = m1x - x 12.

• Power function

A function of the form ƒ(x) = k . x a, where k and a are nonzero constants. k is the constant of variation and a is the power.

• Quotient of complex numbers

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

• Residual

The difference y1 - (ax 1 + b), where (x1, y1)is a point in a scatter plot and y = ax + b is a line that fits the set of data.

• Sinusoidal regression

A procedure for fitting a curve y = a sin (bx + c) + d to a set of data

• Standard representation of a vector

A representative arrow with its initial point at the origin

• Term of a polynomial (function)

An expression of the form anxn in a polynomial (function).

• Wrapping function

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