Anyone know if there's an easy way to get wolfram alpha to understand the short polar notation for complex numbers?
e.g. 656.1?-28.36
I can't seem to find it in the documentation.

I don't think so. WA is basically Mathematica lite, and Mathematica (AFAIK) doesn't understand polar notation directly. The closest I think you're going to get is
656.1(cos(-28.36)+i sin(-28.36))
.

Bugger, I was hoping to be able to write a small conversion program to take equations I've put together in MS equation editor, and effectively dump them into WA for solving.
