**Definitions**
A definition is a rethorical pattern you use to conceptualize words. Definitions usually have a term to be defined, a general class word and a characteristic or characteristics.

=Description= A description is a writing form used to create an impression of an object, person, place, event, process, mechanism, etc. In a description you find many **adjectives** which are the words that will characterize any thing you want to describe.

=Assignment= I. Now select 5 definitions from the on-line mathematics dictionary at [], [|http://www.math.com/school/glossary/glossindex.html], [], or from any other math glossary or dictionary and copy them. Your job will be to identify: a. the term to be defined b. the general class word c. the characteristics

--> **ADDITION:** The operation, or process, of calculating the sum of two numbers or quantities a) Addition b) Calculating c) Operation, sum --> **MULTIPLICATION:** The operation by which the product of two quantities is calculated. a) Multiplication b) Calculating c) Operation, product --> **PI:** The designated name for the ratio of the circumference of a circle to its diameter, represented by the symbol π a) Pi b) name for ratio of the circunference c) symbol π --> **UNIT CIRCLE:** A circle of radius 1 centered at the origin (0,0) of the Cartesian coordinate system. a) Unit Circle b) Circle c) Circle of radius 1 --> **INFINITY:** Greater than any fixed counting number, or extending forever. No matter how large a number one thinks of, infinity is larger than it. Infinity has no limits a) Infinity b) extending forever c) Has no limits
 * Great Job **

II. __**Using your own words**__, write 1 definition about any mathematical terms.

--> **SUBTRACTION:** The inverse operation of addition

 * III. In the text you will find when you click the link below, extract the first paragraph and please find all the characteristics of fractals and underline them. Also find the adjectives and circle them. Be careful ! ! ! **

"A **fractal** has been defined as "a rough or fragmented **geometric shape** that ** can be split into parts **, each of which is (at least approximately) a ** reduced-size ** copy of the whole", a property called self-similarity. Roots of the idea of fractals go back to the 17th century, while mathematically rigorous treatment of fractals can be traced back to functions studied by Karl Weierstrass, Georg Cantor and Felix Hausdorff a century later in studying ** functions ** that were ** continuos but not differentiable **, however, the term fractal was coined by Benoit Mandelbrot in 1975 and was derived from the Latin Fractus meaning "broken" or "fractured." A mathematical fractal is based on an equation that undergoes iteration, a form of feedback based on recursion.There are several examples of fractals, which are defined as portraying exact self-similarity, quasi self-similarity, or statistical self-similarity. While fractals are a mathematical construct, they are found in nature, which has led to their inclusion in artwork. They are ** useful in medicine, soil mechanics, seirmology and technical analysis **."


 * In green ** you can see all the ** characteristics ** of the fractals.

1. A definition of fractal is: a roug** H ** or fragmented geometric shape 2. A description of fractal is: a roug** H ** or fragmented geometric shape that can be split into parts, a reduced-size; and is useful in medicine, soil mechanics, seirmology and technical analysis.
