examples with Sympy

[fluxion]

I thought it could be nice to show some examples rendered
with Sympy.
With unicode:

pprint(Integral(sqrt((1+x)/(x**2+3)),x)+Sum(1/j**2,(j,1,n)))

                       n     
                      ____   
⌠                     ╲      
⎮      ________        ╲   1 
⎮     ╱ x + 1           ╲  ──
⎮    ╱  ──────  dx +    ╱   2
⎮   ╱    2             ╱   j 
⎮ ╲╱    x  + 3        ╱      
⌡                     ‾‾‾‾   
                     j = 1 


With ascii:

pprint(Integral(sqrt((1+x)/(x**2+3)),x)+Sum(1/j**2,(j,1,n)), use_unicode=False)

                        n     
  /                   ____    
 |                    \   `   
 |      ________       \    1 
 |     / x + 1          \   --
 |    /  ------  dx +   /    2
 |   /    2            /    j 
 | \/    x  + 3       /___,   
 |                    j = 1   
/

By comparison, the LaTeX text could be
\int{\sqrt{\frac{x+1}{x^2+3}}dx+\sum_{j=1}^n\frac{1}{j^2}
which I don't have a problem reading it, but... for non-LaTeX users...

Finally, an example of a graphic:

plot(sin(x),(x,-2*pi,2*pi))

0.99830 |       ...                        ...                   
        |      /   \                      /   \                  
        |     /     .                    /     .                 
        |    .                          .                        
        |            .                          .                
        |   .                          .                         
        |             .                          .               
        |  .                          .                          
0.05872 | -------------.--------------------------.--------------
        | .             .            .             .            /
        |                           .                          . 
        |                .                          .            
        |                          .                          .  
        |                 .                          .           
        |                         .                          .   
        |                  .     /                    .     /    
        |                   \   /                      \   /     
-0.9983 |                    ...                        ...      
          -6.28319                   0                          6.28319

In this case we seem to get the same result with ascii and unicode,
or maybe Sympy does not distinguish for plotting, although both
pprint(plot(sin(x),(x,-2*pi,2*pi)),use_unicode=False)
and 
pprint(plot(sin(x),(x,-2*pi,2*pi)))
seem to be accepted by Sympy.

Is this enough for math & data? What do you think?
