A notation question:
The polar form of a complex number is $$r e^{iθ}$$.

Which, if any, of these are in polar form?

A) $$5e^{2i}$$
B) $$2e^{i\pi}$$
C) $$(4+\sqrt{2})e^i$$
D) $$e^{(4+\sqrt{2})i}$$
E) $$e^{0i}$$
F) $$e^0$$
G) $$1$$

@christianp I would say all but D). But only B) would also be a respectable answer.

@christianp oh wait I didn't see those parens, then all of them.

@christianp I agree with @maralorn, tho I feel this is one of those times where using $$\exp(z)$$ is better than $$e^z$$.

@tpfto @maralorn ha, I used exp on Twitter because I can't do superscripts

@christianp I have no issue with saying they all are in polar form

@christianp I dislike C and D, and A is an insult to reasonable angles, but all of them.

@kimreece @christianp how else would you represent a complex number with a phase of one radian? ;D
