wolfram alpha complex angles
« on: April 07, 2013, 05:17:12 am »
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.

Try this:
Code: [Select]
656.1*cis(-28.36)

 :palm: Yes, cis. I should not have forgotten that.  ::)
