It's true for [math] x \in \mathbb{C} [/math] too isn't it? There may be some other sets on which sin and cos can be meaningfully defined, in which it isn't true, but I doubt it. Regardless, sage still won't simplify given this information. I've realize that there's a couple of other functions: simplify_full and simplify_trig which actually do have the intended effect though.
