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

• Annuity

A sequence of equal periodic payments.

• Average rate of change of ƒ over [a, b]

The number ƒ(b) - ƒ(a) b - a, provided a ? b.

• Binomial coefficients

The numbers in Pascal’s triangle: nCr = anrb = n!r!1n - r2!

• Bounded below

A function is bounded below if there is a number b such that b ? ƒ(x) for all x in the domain of f.

• Complements or complementary angles

Two angles of positive measure whose sum is 90°

• Continuous at x = a

lim x:a x a ƒ(x) = ƒ(a)

• Difference identity

An identity involving a trigonometric function of u - v

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

• Identity matrix

A square matrix with 1’s in the main diagonal and 0’s elsewhere, p. 534.

• Initial value of a function

ƒ 0.

• Mean (of a set of data)

The sum of all the data divided by the total number of items

• Pascal’s triangle

A number pattern in which row n (beginning with n = 02) consists of the coefficients of the expanded form of (a+b)n.

• Product of complex numbers

(a + bi)(c + di) = (ac - bd) + (ad + bc)i

• Projection of u onto v

The vector projv u = au # vƒvƒb2v

• Quotient of complex numbers

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

See Multiplicative inverse of a real number.
