How can I draw the complex number $z_1 = 2e^{{piover6}i -1}$
$begingroup$
I'm not sure how to draw the following number in the complex plane:
$$z_1 = 2e^{({piover6}i -1)}$$
My guess would be that you seperate the exponents:
$$z_1 = 2e^{({piover6}i)} e^{-1}$$
To get:
$$z_1 = frac{sqrt 3}{e} + frac{1}{e}i$$
So $ operatorname{Re}(z_1) =frac{sqrt 3}{e}$ and $ operatorname{Im}(z_1) =frac{1}{e}$.
Is this correct? This is part of a previous exam question, but my teacher doesn't provide any answers.

This is correct. You get the complex number $z$ with modulus $frac2e$ and argument $frac{pi}6$.
