Key Calculus Terms and definitions covered in this textbook
• Equation

A statement of equality between two expressions.

• Focal width of a parabola

The length of the chord through the focus and perpendicular to the axis.

• Imaginary axis

See Complex plane.

• Invertible linear system

A system of n linear equations in n variables whose coefficient matrix has a nonzero determinant.

• Lower bound test for real zeros

A test for finding a lower bound for the real zeros of a polynomial

• Minute

Angle measure equal to 1/60 of a degree.

• Monomial function

A polynomial with exactly one term.

• 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.

The measure of a central angle whose intercepted arc has a length equal to the circle’s radius.

• 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).

• Reflection through the origin

x, y and (-x,-y) are reflections of each other through the origin.

• Secant

The function y = sec x.

• Statute mile

5280 feet.

• Sum of a finite geometric series

Sn = a111 - r n 2 1 - r

• Summation notation

The series a nk=1ak, where n is a natural number ( or ?) is in summation notation and is read "the sum of ak from k = 1 to n(or infinity).” k is the index of summation, and ak is the kth term of the series

• Tangent

The function y = tan x

• Translation

See Horizontal translation, Vertical translation.

• Unbounded interval

An interval that extends to -? or ? (or both).

• Vertical component

See Component form of a vector.

• Vertical line

x = a.
