yup

Isn't that B?

Yes, that's right

ah cool.

So for A it would be: -4(cos(5pi/6)+isin(5pi/6))

What exactly does it look like then?

|dw:1434408649310:dw|
See the rectangle I drew above. That is point B in Polar form.

See - https://en.wikipedia.org/wiki/Euler%27s_identity#Explanation

$$
r\exp^{i\theta}=r\left(\cos\theta+i\sin\theta \right)
$$

Should I write it as (r, theta)? I never formally learned e^i theta

Yes, that is also in Polar form

Thanks! That was helpful!

$$
\text{Rectangular: }(r\cos\theta,r\sin\theta)\\
\text{Polar: }(r,\theta)
$$

Gotcha, thanks for clearing that up! :)

I gave you a medal

It was helpful that you knew the basics!

Oh wait, one last question

If the second is in Polar form, it would be invalid because r > 0.

That is odd, my worksheet says to graph it. Should I just write it in the -3 area?

That is true. Do you think they mean that it should be graphed on the 3 mark?

Here's is the plot of that point - http://www.wolframalpha.com/input/?i=plot+%28-3%2Cpi%2F3%29

Part 1 should be (4, 5pi/6) right?

Alright, thanks!

You're welcome

:)
