I'm using sympy to generate some latex output, and I would like to create
an expression by multiplying several matrices, but I don't want it to
simply the expression.
A simple example:
I have
x, y, ori = sympy.symbols('x y ori')
T = Matrix([
[1, 0, -x],
[0, 1, -y],
[0, 0, 1]])
R = Matr
I have a matrix equation where it would be useful for the output to have a
-theta inside a sine operation. However, whenever I type sympy.sin(-theta)
it always expands to -sin(theta). Is there any way to disable this?

I think its a pretty good idea. I'm not a sympy dev, but I stumbled on this
thread because I was looking for some way to do this.

I saw under http://docs.sympy.org/dev/tutorial/simplification.html#powsimp
that it is impossible to combine radicals using powersimp:
"This means that it will be impossible to undo this identity with powsimp(),
because even if powsimp() were to put the bases together, they would be

I'm having an issue where an expresion with sympy.tensor.Indexed variables
does not seem to simplify correctly.
It is likely that I'm just doing something incorrect, so I was wondering if
anyone could help me figure this out.
