Thank you very much :)

Let's rewrite your submission to correct the English! My teacher and my classmates have decided to transform our classroom into a mathematics lab. We have to paint the walls with special numbers, a number line, some magic squares, and symbols related to all levels of mathematics. Each student must contribute something different. I wanted to post pi to one hundred places or show the Pythogrean Theorem. I thought about graphing some polynomials or showing Euler's Formula. I love trigonometric functions so I think I will put up the proof of an identity. The curl of the curl is equal to the gradient of the divergence minus the Laplacian. http://www.youtube.com/watch?v=P4edqL1r4DQ
