I can't understand, why do sin(x) and tan(x) return wrong values when I put Math.PI as x. It shows 1,22 for sin and -1,22 for tan, when it should be 0 in both cases?

How exactly do I access the files I saved in the code playground? Do you have to make them public in order for them to save? Since I've been trying to save things, but I can't find where they show up. Thanks.
