Hi, I plan to heavily use a function generated with lambdify from a sympy expression which has repeated occurences of some subexpressions. Specifically it will have a lot of cosine and sine expressions with the same arguments. I don't know if lambdify can notice this pattern and evaluate that subexpression only once, or if it will call it (the numeric sine and cosine functions) as many times as it appears, or if I have to specify it somehow. I am afraid that it would mean a considerable performance loss if, for example, it will have to call 2-3 times as many trigonometric functions as a hand-written code, since I plan to use it a lot. Can somebody provide me some information?
