Is there a cis (CosX + iSinX) Button in CASIO graphic calculators ? if so where its ? if no is there any turn around for it ?

So, entering 2∠30 is equivalent to entering $2\text{ cis }30°$.
$cis(x)$ 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? –  please delete me Mar 2 '11 at 7:14
