### Ezmath

1. 1. Ezmath @neizod
2. 2. Who am I?
3. 3. neizod
4. 4. What is Ezmath?
5. 5. simple math syntax
6. 6. display as fully symbolic mathematical notation
7. 7. on web
8. 8. Why?
9. 9. old fashion blackboard http://www.energytribune.com/articles.cfm/2469/Understanding-E-=-mc2
10. 10. when it comes to internet
11. 11. when it comes to internet e.g. I want this
12. 12. plain-text x = (-b +- sqrt(b^2 - 4ac)) / 2a
13. 13. picture
14. 14. GUI math input Windows 7 Math Input Panel
15. 15. MathML
16. 16. LaTeX
17. 17. Introducing to MathJax
18. 18. MathJax
19. 19. So, lets focus on the syntax!
20. 20. easy, flexible, and powerful
21. 21. E = mc^2
22. 22. x = (-b +- sqrt(b^2 - 4ac)) / (2a)
23. 23. lim sum f(a + i Delta x) Delta x from (i=1) to n where (n -> infinity) = int f(x) _dx from a to b ; ___ Delta x = (b-a)/n
24. 24. [x'; y'; 1] = [cos theta, sin theta, 0; -sin theta, cos theta, 0; 0, 0, 1] [x; y; 1]
25. 25. &quot;&quot;[15]^32 &quot;P&quot; --> &quot;&quot;[16]^32 &quot;S&quot; + beta^- +v
26. 26. Syntax's Concept
27. 27. 1. Start from smallest part
28. 28. Numbers 2.71828183...
29. 29. Variable pi
30. 30. Symbol +-
31. 31. Text &quot;this is ezmath&quot;
32. 32. 2. Adding attributes into it
33. 33. Index m[i][j]
34. 34. Exponentiation x^2
35. 35. 2. Adding attributes into it
36. 36. Square root sqrt 2
37. 37. Vector vec A
38. 38. 3. Group them into sentence...
39. 39.   c^2 = a^2 + b^2
40. 40. Sometimes, complex sentence
41. 41. Fraction a / (sin A)
42. 42. Choose (n - 1 choose r)
43. 43. Matrix [a, b; c, d]
44. 44. Integral int f(x) _dx from a to b
45. 45. That's It!
46. 46. How does it work?
47. 47. 1. PHP Hello world! $$x = (-b +- sqrt(b^2 - 4ac)) / (2a)$$ Welcome to Mathematics
48. 48. 2. Flex x = ( - b +- sqrt( b ^ 2 - 4 a c ) ) / ( 2 a )
49. 49. 3. Bison x =   frac{ - b  pm  sqrt{ b ^{ 2 } -  4 a c } }{ 2 a }
50. 50. 4. PHP (again) Hello world! [ x = frac{-b pm sqrt{b^{2} - 4ac}}{2a} ] Welcome to Mathematics
51. 51. 0. Browser input Hello world! $$x = (-b +- sqrt(b^2 - 4ac)) / (2a)$$ Welcome to Mathematics
52. 52. 5. MathJax (done)
