Key Calculus Terms and definitions covered in this textbook
• Additive inverse of a complex number

The opposite of a + bi, or -a - bi

• Amplitude

See Sinusoid.

• Angle

Union of two rays with a common endpoint (the vertex). The beginning ray (the initial side) can be rotated about its endpoint to obtain the final position (the terminal side)

• Common difference

See Arithmetic sequence.

• Difference of functions

(ƒ - g)(x) = ƒ(x) - g(x)

• 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

• Five-number summary

The minimum, first quartile, median, third quartile, and maximum of a data set.

• Frequency

Reciprocal of the period of a sinusoid.

• Graph of an equation in x and y

The set of all points in the coordinate plane corresponding to the pairs x, y that are solutions of the equation.

• Half-plane

The graph of the linear inequality y ? ax + b, y > ax + b y ? ax + b, or y < ax + b.

• Hypotenuse

Side opposite the right angle in a right triangle.

• Left-hand limit of f at x a

The limit of ƒ as x approaches a from the left.

• Normal distribution

A distribution of data shaped like the normal curve.

• Parametric curve

The graph of parametric equations.

• Polar coordinates

The numbers (r, ?) that determine a point’s location in a polar coordinate system. The number r is the directed distance and ? is the directed angle

• Quartile

The first quartile is the median of the lower half of a set of data, the second quartile is the median, and the third quartile is the median of the upper half of the data.

• Rational zeros theorem

A procedure for finding the possible rational zeros of a polynomial.

• Second quartile

See Quartile.

• Solution of an equation or inequality

A value of the variable (or values of the variables) for which the equation or inequality is true

• Standard form of a complex number

a + bi, where a and b are real numbers
