The ratio of the length of the side adjacent to
an acute angle to the length of the hypotenuse. The cosine of an angle is written as COS. See
also circular function.
What is Cotangent?
100
A measure of central tendency denoted by x , read “x bar”, that is calculated by adding
the data values and then dividing the sum by the number of values. Also known as the arithmetic
mean or arithmetic average.
What is mean?

line (called the directrix)
What is parabola

What is angle
200
In any triangle the ratio of one side to the sine of its opposite angle is equal to the ratio of any other side and the sine of its opposite angle.
What is Law of sines?
200
A measure of central tendency that is, or indicates, the middle of a data set when the
data values are arranged in ascending or descending order. If there is no middle number, the
median is the average of the two middle numbers.
What is median ?
200
A graphical display of statistical data plotted as points on a coordinate plane to
show the correlation between two quantities.
What is scatter plot

A measure of central tendency that is given by the data value(s) that occur(s) most
frequently in the data set.
What is mode
300
Various ways, i.e., graphically, numerically, algebraically,
geometrically, and verbally, to present, interpret, communicate, and connect mathematical
information and relationships.
What is multiple representations
300
The quotient of two polynomials in the form A/B ,
where A and B are polynomials and B ≠ 0.
What is rational expression
300
Two coplanar angles that share a common vertex and a common side but
have no common interior points.
What is adjacent angles
400
For a given acute angleθ in a right triangle, the ratio of the length of the hypotenuse
of the triangle to the side opposite the acute angle. Also the reciprocal of the sine ratio of the
given angle, written as csc.
What is cosecant?
400
A summary statistic that indicates the typical value or center of an organized data set. The three most common measures of central tendency are the mean,
median, and mode.
What is measure of central tendency ?

are solutions to a system of equations.
What is graphical solution of a system of equations
400
Any number that can be expressed as a ratio in the form a/
