Jupyter notebook, output more than one expression from cell

I want to show the result of an intergation, done in SymPy as an Output in Jupyter with MathJax. Everything works, but I wanted to adjust the output a bit, so that instead of the following: Current Ouput

I would get this output: Desired output (Please ignore the arctan() thing.)

I have tried to achieve this by doing something like that:

from IPython.display import Math
from sympy.interactive import printing
printing.init_printing(use_latex=True)
f=(-2*x-1)/(pow(x,2)+2)
Math('F(x)=')
integrate(f,x)
Math('+C')

But unfortunately only the last output of the cell is shown, so my question is if it is possible to merge multiple outputs into one?

You might also want to try looking at the "Display Math Operation" function I have been fiddling with. You can try it on mybinder:Binder. It accepts things like dmo(p = n*R*T/V) makes the assignment to p and outputs a typeset version of the latex string p=\frac{nRT}{V}. The eventual goal is to get dmo(diff(p,T)) to output a typeset version of \frac{\partial p}{\partial T} = \frac{nR}{V}. When I have more time, I am going to dig into the rendering in sympy and see if I can get options put into the actual operations, such as diff and int. The special Derivative and Integrate operations were also designed for rendering just those operations.

Follow the link in binder to the github repository if you have specific comments or suggestions.

You can use printing.default_latex, which returns the expression in LaTex as a string:

from IPython.display import Math
import sympy
from sympy.interactive import printing

x = sympy.var('x')
f=(-2*x-1)/(pow(x,2)+2)

Math('F(x) = {} + C'.format(printing.default_latex(sympy.integrate(f, x))))
