I would really like to help you, but I cannot deal with the fact you are saddled with a totally outdated system.

Almost all modern mathematics does not recognized "*two pairs of polar coordinates*" as meaningful.

Moreover, we also insist that , nobody uses degrees in mathematics.

Now if you can accept those conventions then has polar form;

and .

**You might tell your instructor to get with the modern usage.** - April 16th 2013, 07:04 PMSorobanRe: Help with Polar Coordinates
Hello, ambitionty9!

I agree with Plato completely.

However, if weuse this outdated notation . . .*must*

We find that: .

One pair of coordinates is: .
