Hello John and Enri,

Hope you two are having a relaxing summer break. I have a few suggestions for the page:

**Image and Image Description (at the very top)**

- I really like how you created your own image for the page. Most people just copy and paste from some website.
- In the image description, mention how the fractal has a starting point (the starting square) and how it is constructed in a particular order.
- In the image description at the very top, say “The space between the squares is a right triangle” rather than “The space between the squares in each iteration creates a right triangle”.

**Basic Description**

- Nice job on creating the gif! If you have the time, try to crop the gif so that only the Pythagorean Tree is there (not the surrounding window. This just makes it look prettier. Since GSP sucks at making gifs, I suggest drawing a large rectangle in GSP that surrounds the entire Tree. You can use this rectangle to crop the images to create a smooth gif. If you need help, just let me know.
- Mainly watch out for verboseness (examples below).
- 2nd sentence: Write “The hypotenuse of the triangle is directly connected to the square” instead of “The hypotenuse of the triangle must always be the one that is directly connected to the square”.
- 3rd sentence: Write “the legs of it” rather than the “legs of said triangle”.
- 4th sentence: Write “so the area of each new square is less than the area of the old square” instead of “so the square are smaller than the big one”.
- Remove the 7th sentence: “When the angles of the triangle are changed, one is made bigger, and the other is made smaller.”
- Change the 8th to the last sentence from “so the sides change too” to “so changing the angle changes the side”.

**A More Mathematical Explanation**

- Visual Suggestions

- Whenever you write expressions and equations outside of the math environment, make sure to only italicize the variables; don’t italicize numbers. For instance, make sure the 2 superscript in
*s*^{2}is not in the italics; in other words put the*only around the*s*. This change applies to numerical constants as well (0.5*s*rather than*0.5s*).* - For the sines and cosines, write them in the math environment as \sin or \cos rather than just typing sin or cos.
- Whenever you multiply a constant to sine or cosine, you don’t need the * between it. If you make the previous fix, then the sin and cos will look different enough from the normal math environment letters that the reader won’t be confused.
- Fix the equation Proxy-Connection : keep-aliveCache...
- Crop out the white spaces surrounding the bottom 3 images. I suggest you place the images as thumbnails to the right or left so the text will curve around it. Let me know if you need help.
- This is just a personal thing of mine. I just don’t like how the * looks anywhere; I prefer parenthesis, brackets, or even the center dot far more. If both of you are fine with how it looks, then leave it.

- At the start of the mathematical explanation, rewrite the proof of how the sum of the area of the smaller squares equals the area of the larger square. You start with the Pythagorean Theorem, then show proving it is related to it. Instead, try to start with deriving the sides of the squares first (express
*a*and*b*in terms of*θ*and*s*), then showing how the sum of the areas is equal to the area of the larger square. THEN state how the Pythagorean Theorem is related to all this. - When you talk about finding the general equation of the area for any iterations and give examples about it, remember to put () around
*n*+ 1 since you’re multiplying*s*^{2}by that entire number (order of operations). - You should write your NOTE: (right under the second to last image) under the derivation of the general equation because it’s an assumption of the equation.

Finally, I see two main options for the history of the tree:

1. Expand on it and make it a new section (history of something is not part of a more mathematical explanation).

2. Remove it.

That’s it for now. Great job on the page so far, and good luck. --Xtian1 11:50, 2 July 2013 (EDT)
