$2 [cos (\frac{17 π}{12}) + i sin (\frac{17 π}{12})]$ $2[cos ((17pi)/12)+ i sin ((17pi)/12)]$

Use Euler's formula for complex numbers $e^{i t} = cos t + i sin t$ $e^(it)= cos t +i sin t$

Accordingly $2 e^{\frac{17 π i}{12}} = 2 [cos (\frac{17 π}{12}) + i sin (\frac{17 π}{12})]$ $2e^[(17pii)/12)=2[cos ((17pi)/12)+ i sin ((17pi)/12)]$
