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?

Try with evaluate flag. sin(-theta, evaluate=False) should give sin(-theta).

Hello guys
I use python (notebook, sympy, pyspice and matplotlib are a very good
team) to design some electronic projects allowing me to have almost
everything in only one place.
I tried for a while to play with the units but I was unable to go
further. Today I asked a question [0] in Stack Over
Have you looked at the new sympy.physics.unitsystems module? It should be
more flexible than the sympy.physics.units module.

Thank you for your suggestion, Aaron. I tried to look at it, but I was
not able to find the path to the solution. Do you have a tip?
