What is Ezmath?

simple math syntax

 

display as fully symbolicmathematical notation

e.g. I want this

x = (-b +- sqrt(b^2 - 4ac)) / 2a

Introducing to MathJax

 

MathJax

So, lets focus on the syntax!

 

easy, flexible, and powerful

 

E = mc^2

x = (-b +- sqrt(b^2 - 4ac)) / (2a)

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

[x'; y'; 1] = [cos theta, sin theta, 0; -sin theta, cos theta, 0; 0, 0, 1] [x; y; 1]

""[15]^32 "P" --> ""[16]^32 "S" + beta^- +v

Syntax's Concept

 

1. Start from smallest part

 

Numbers

2.71828183...

Variable

pi 

Symbol

+-

Text

"this is ezmath"

2. Adding attributes into it

 

Index

m[i][j]

Exponentiation

x^2

2. Adding attributes into it

 

Square root

sqrt 2

Vector

vec A

3. Group them into sentence...

 

 

c^2 = a^2 + b^2

Sometimes, complex sentence

 

Fraction

a / (sin A)

Choose

(n - 1 choose r)

Matrix

[a, b; c, d]

Integral

int f(x) _dx from a to b

That's It!

 

How does it work?

 

1. PHP

Hello world!$$ x = (-b +- sqrt(b^2 - 4ac)) / (2a) $$

Welcome to Mathematics

2. Flex

x = (-b +- sqrt(b^2 - 4ac)) / (2a)

3. Bison

x = \frac{-b \pm \sqrt{b^{2} - 4ac}}{2a}

4. PHP (again)

Hello world!\[ x = \frac{-b \pm \sqrt{b^{2} - 4ac}}{2a} \]

Welcome to Mathematics

0. Browser input

Hello world!$$ x = (-b +- sqrt(b^2 - 4ac)) / (2a) $$

Welcome to Mathematics

5. MathJax (done)
