Key Calculus Terms and definitions covered in this textbook
• Binomial coefficients

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

• Commutative properties

a + b = b + a ab = ba

• Data

Facts collected for statistical purposes (singular form is datum)

• Degree

Unit of measurement (represented by the symbol ) for angles or arcs, equal to 1/360 of a complete revolution

• Discriminant

For the equation ax 2 + bx + c, the expression b2 - 4ac; for the equation Ax2 + Bxy + Cy2 + Dx + Ey + F = 0, the expression B2 - 4AC

• Exponential function

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

• Extracting square roots

A method for solving equations in the form x 2 = k.

• Frequency

Reciprocal of the period of a sinusoid.

• Horizontal component

See Component form of a vector.

See Polynomial function in x

The eight regions of space determined by the coordinate planes.

• One-to-one rule of exponents

x = y if and only if bx = by.

• Pseudo-random numbers

Computer-generated numbers that can be used to approximate true randomness in scientific studies. Since they depend on iterative computer algorithms, they are not truly random

• Quartic function

A degree 4 polynomial function.

• Remainder polynomial

See Division algorithm for polynomials.

• Triangular number

A number that is a sum of the arithmetic series 1 + 2 + 3 + ... + n for some natural number n.

• x-coordinate

The directed distance from the y-axis yz-plane to a point in a plane (space), or the first number in an ordered pair (triple), pp. 12, 629.
