IPython Notebook Sympy Math Rendering
Question: I have just started with using IPython Notebook and have been fascinated by
its power. I have been using a few examples available on the net to get
started with. I was following this tutorial:
<http://nbviewer.ipython.org/url/finiterank.com/cuadernos/suavesylocas.ipynb>
but the maths output is not getting rendered as expected. Below is the my code
and the output:

    
    
    In [30]:
    
    %load_ext sympyprinting
    %pylab inline
    
    from __future__ import division
    import sympy as sym
    from sympy import *
    
    init_printing()
    
    x,y,z=symbols("x y z")
    k,m,n=symbols("k m n", integer=True)
    
    The sympyprinting extension is already loaded. To reload it, use:
      %reload_ext sympyprinting
    
    Welcome to pylab, a matplotlib-based Python environment [backend: module://IPython.kernel.zmq.pylab.backend_inline].
    For more information, type 'help(pylab)'.
    
    In [31]:
    
    t = sin(2*pi*x*(k**2))/ (4*(pi**2)*(k**5)) + (x**2) / (2*k)
    t
    Out[31]:
      2      ⎛     2  ⎞
     x    sin⎝2⋅π⋅k ⋅x⎠
    ─── + ─────────────
    2⋅k         2  5   
             4⋅π ⋅k   
    

I have tried other examples also, and they are also not getting rendered
properly. Where am I going wrong?


Answer: I had the same problem. Try

    
    
    from sympy.interactive import printing
    printing.init_printing(use_latex=True)
    

instead of

    
    
    %load_ext sympyprinting
    

I am using sympy 0.7.2
