From the instruction manual:

product of two polar-form complex numbers

So, entering 2∠30 is equivalent to entering $2\text{ cis }30°$.

$\text{cis}(x)$ is equal to $e^{ix}$.

    Have you turned on complex mode on the calculator? (Set up $\to$ Complex Mode). When does it return an error? In the graph mode?2011-03-02
