Key Calculus Terms and definitions covered in this textbook
• Amplitude

See Sinusoid.

• Annual percentage yield (APY)

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

• Argument of a complex number

The argument of a + bi is the direction angle of the vector {a,b}.

• Causation

A relationship between two variables in which the values of the response variable are directly affected by the values of the explanatory variable

• 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

• Course

See Bearing.

• Fibonacci sequence

The sequence 1, 1, 2, 3, 5, 8, 13, . . ..

• Frequency (in statistics)

The number of individuals or observations with a certain characteristic.

• Higher-degree polynomial function

A polynomial function whose degree is ? 3

• Infinite discontinuity at x = a

limx:a + x a ƒ(x) = q6 or limx:a - ƒ(x) = q.

• Nappe

See Right circular cone.

• Natural logarithmic regression

A procedure for fitting a logarithmic curve to a set of data.

• Parametric equations for a line in space

The line through P0(x 0, y0, z 0) in the direction of the nonzero vector v = <a, b, c> has parametric equations x = x 0 + at, y = y 0 + bt, z = z0 + ct.

• Polar axis

See Polar coordinate system.

• Random numbers

Numbers that can be used by researchers to simulate randomness in scientific studies (they are usually obtained from lengthy tables of decimal digits that have been generated by verifiably random natural phenomena).

• Rational function

Function of the form ƒ(x)/g(x) where ƒ(x) and g(x) are polynomials and g(x) is not the zero polynomial.

• Second quartile

See Quartile.

• Singular matrix

A square matrix with zero determinant

• Solve algebraically

Use an algebraic method, including paper and pencil manipulation and obvious mental work, with no calculator or grapher use. When appropriate, the final exact solution may be approximated by a calculator

• Sum of a finite geometric series

Sn = a111 - r n 2 1 - r
