That's not how Anscos(angle(Ans works. angle( returns pi for negative numbers and 0 for nonnegative numbers. cos( returns -1 for pi and 1 for 0. Therefore, you're multiplying the number by its sign function, except for 0 which doesn't matter.

There's also Anscos(angle(Ans at 5 bytes, which is interesting.
