    I strongly advice you to get to work.... Those activities will not be carrected because they're late.
    Please do the activity you have still time to do (comparison and contrast (5pts)

    Comparison & Contrast.
    1)
    Comparison:
    - A Julia set is almost the same thing. It is defined to be : the set of all the complex numbers, z, such that the iteration of f(z) -- > z 2 + c is bounded for a particular value of c. Again, more simply put it is the graph of all the complex numbers z, that do not go to infinity when iterated in f(z) -- > z 2 + c, where c is constant.
    Contrast:
    - Both Mandelbrot and Julia sets are types of fractals. However, these are more complicated fractals then the other fractals that have been mentioned (such as the Sierpinski's triangle).
    - For the Mandelbrot and Julia sets it can be proved (through a very complex proof) that if the distance, on the Cartesian plane (remember we are using complex numbers here), between the origin and a point resulting from the iteration of some initial value is greater than 2 then the behavior of that initial value is that it will go to infinity. If, however, after numerous iterations (possibly hundreds, thousands or more) the distance between that origin and the point is never greater than two, it is said that this point is bounded.
    - It should be understood that these are simply the basic definitions of the two sets. The function that is iterated can be practically anything, as long as it uses complex numbers. Thus the basic difference between the Mandelbrot set and Julia set is that in any Mandelbrot set, you are plotting various values of c on a Cartesian plane, whereas for a Julia set, you are plotting various starting values of z, and c is kept constant.
    To know if something is comparison or contrast, i noticed keywords, en comparison: almost, and contrast: however and whereas.
    2)
    Contrast:
    - The people use bar graphs to show of connections between two or more thing; however, if you need show the data into groups is better box plot.
    Comparison:
    - The box plots are used almost how bar graphs, but the bar graphs are more common.

    "Dr. Quantum: Flatland”
    - What do you think the video will be about?
    I think that the video will talk about dimensions or surfaces, something like a XY plane.
    - What do you think "flatland" means?
    I believe that flatland means something related with ground or land, and that it has no mountains or other elevations.
    - Who are the main characters in the video?
    The main characters are the circle and Dr. Quantum.
    - What's the difference between the worlds in which the characters live in?
    In the circle's world the people can't see up or down.
    - What does Dr. Quantum decide to do?
    The doctor decides to show the 3D world to the circle.

    1)
    - Area (term) is the number (general class word) of square units needed to cover a surface (the characteristics).
    - Bar graph (term) is a diagram (general class word) showing a system of connections or interrelations between two or more things by using bars(the characteristics).
    - Box plot (term) also called box-and-whisker plot, this graph (general class word) shows the distribution of data by dividing the data into four groups with the same number of data points in each group. The box contains the middle 50% of the data points and each of the two whiskers contain 25% of the data points (the characteristics).
    - Complementary angles (term) two angles (general class word) that have a sum of 90 degrees (the characteristics).
    - Decimal number (term) a fraction (general class word) where the denominator is a power of ten and is therefore expressed using a decimal point. For example: 0.37 is the decimal equivalent of 37/100 (the characteristics).
    2) Hypotenuse (term) is a side (general class word) that opposes to the 90 degrees angles in a rectangle triangle (the characteristics).

Roots of mathematically rigorous treatment of fractals can be traced back to functions studied by Karl Weierstrass, Georg Cantor and Felix Hausdorff in studying functions that were continuous but not differentiable; however, the term fractal was coined by Benoît 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 (the characteristics)
    The bold text is the definition, then follows the description.
    To find the description, I identify the adjectives which characterize the fractals.
    4) A rectangle triangle has three sides, two calls “Leds”, and other “hypotenuse”, this kind of triangles are used in science like physics and mathematics for their usefulness, one of the largest applications are the vector's projections.

    Classification
    Assignment
    I. Visit the following link and draw a graphic organizer showing the classification of triangles. Work only with the types of triangles.
    http://en.wikipedia.org/wiki/Triangle#Types_of_triangles
    II. Write the classification of the mathematical term you defined and described in the last wiki activity
    By relative lengths of sides
    By internal angles
    In an equilateral triangle all sides have the same length. An equilateral triangle is also a regular polygon with all angles measuring 60°.[1]

    equilateral triangle
    {file:///C:/DOCUME%7E1/ADMINI%7E1/CONFIG%7E1/Temp/msohtml1/01/clip_image004.gif} Right triangle
    Right
    A triangle that has one of its interior angles measuring 90°
    In an isosceles triangle, two sides are equal in length.[2][3] An isosceles triangle also has two angles of the same measure; namely, the angles opposite to the two sides of the same length

    isosceles triangle
    {file:///C:/DOCUME%7E1/ADMINI%7E1/CONFIG%7E1/Temp/msohtml1/01/clip_image008.gif} Obtuse triangle
    Obtuse
    A triangle that has one angle that measures more than 90° i
    In a scalene triangle, all sides are unequal.[4] The three angles are also all different in measure. Some (but not all) scalene triangles are also right triangles.

    Acute
    A triangle that has all interior angles measuring less than 90°

    "Geometry Tips: What Is the Pythagorean Theorem?"
    - What do you think this video will be about?
    -
    I think that video talks about triangles, proportions and some of the Life of Pythagoras.
    - Mention five words you think you might listen to in the video.
    Geometry
    Plus
    Square root
    Hypotenuse
    Squared
    - What is the pitagoream theorem?
    Is a tool that is used to calculate the hypotenuse or the legs of a triangle.
    - Why is it said to be exclusive?
    Because the triangle needs to be squared.
    - What is a hypothenuse?
    Is the side opposite the 90 degree angle.
    - What is the name of the other sides of a rectangle triangle?
    They are called leds.
    - What steps he uses to solve the problem on the video?
    1- Identifies the angle of 90 degrees.
    2- Take the values of the legs.
    3- Using the formula (Hyp)ˆ2 = (Led)ˆ2 + (Led)ˆ2 , is the value of the hypotenuse.
