When try to find a complex number in rectangular form there are two ways I do it.

A. Put it in exponential form and let my calculator do it.

B. Use:

$\displaystyle r cis x = r cos x + ir sin x$

Now with $\displaystyle \sqrt{3}cis3$ I get two different answers

A. -1.7147 + 0.2444i

B. 1.7297 + 0.0906i

Which is right? Is my rule for B wrong?
