我刚刚开始使用 IPython Notebook,并被它的强大功能所吸引。我一直在使用网络上的一些示例来开始使用。我正在关注本教程: http: //nbviewer.ipython.org/url/finiterank.com/cuadernos/suavesylocas.ipynb但数学输出未按预期呈现。下面是我的代码和输出:
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
我也尝试了其他示例,但它们也没有正确呈现。我哪里错了?
