Enjoy MATH with Keyboard.

### Differentiate

```
d/dx(cos(x))
=> ( - sin( x ) )

d/dx(log(x))
=> ( 1 / x )

# You can omit parentheses

d/dy y^2                        
=> ( 2 * y )

d/dy xy                       
=> ( x )
```


### Integrate

```
S(log(x)dx)[0..1]
=> - oo

S(sin(x)dx)[0..pi]
=> 2.0

S(cos(x)dx)[0..pi]                       
=> 0.0
```


### Matrix

```
(1 2 3; 4 5 6)
=> (1 2 3; 4 5 6)

(1 2 3; 4 5 6) + (1 2 3; 4 5 6)
=> (2 4 6; 8 10 12)

(1 2 3; 4 5 6) * (1 2 3)
=> (14 32)
```

### Function
```
f(x, y) = xy
f(1, 2)
=> 2
```
