New issue 3089 by [email protected]: Math.sin(-x) is not -Math.sin(x)
http://code.google.com/p/v8/issues/detail?id=3089
Let x = Math.pow(2,120)
Math.sin(x) = 0.2446152181180111
Math.sin(-x) = -0.2970278622893754
You can argue whether there's any significance to Math.sin(x), but since
sin(-x) = -sin(x) for all x, Math.sin should satisfy the same identity for
any real x.
Math.tan has the same issue, but it will be fixed if Math.sin is fixed.
