Definition
In a right triangle with acute angle A, the cosine of A =
the measure of the leg adjacent to A .
the measure of the hypotenuse
In a right triangle with acute angle A, the cotangent of A =
the measure of the leg adjacent to A .
the measure of the leg opposite A
Two angles in standard position that have the same terminal
side.
A specific case which proves a statement false.
A method that uses determinants to solve a system of linear
equations.

products are 2 × 12 and 3 × 8.
The product in which a number is a factor three times. Example:
The cube of 2, or 2 cubed, is 8 because 2 × 2 × 2 = 8.
A solid figure with six square faces.
A function that can be described by an equation of the form y
=ax3 + bx2 + cx + d, where a ≠ 0.
Used to measure volume and tells the number of cubes of a
given size needed to fill a three-dimensional figure.
A histogram organized using a cumulative frequency table.
A table in which the frequencies are accumulated for each item.
A customary unit of capacity equal to 8 fluid ounces.
A solid figure whose bases are formed by congruent circles in
parallel planes and whose lateral surface is curved. The
segment whose endpoints are the centers of the circular bases
is called the axis of the cylinder. The altitude is a segment
perpendicular to the bases with an endpoint in each base.
Numerical information gathered for statistical purposes.
A polygon having ten sides.
