Question 1

Dans le plan complexe, on donne le point $B$ d'affixe $\mathrm{i}.$

L'écriture complexe de la rotation de centre $B$ et d'angle $-\dfrac{\pi}{3}$ est :

$z'=\left(\dfrac{1}{2}-\mathrm{i}\dfrac{\sqrt{3}}{2}\right)z-\dfrac{\sqrt{3}}{2}+\dfrac{1}{2}\mathrm{i}$

$z'=\left(\dfrac{1}{2}-\mathrm{i}\dfrac{\sqrt{3}}{2}\right)z+\dfrac{\sqrt{3}}{2}+\dfrac{1}{2}\mathrm{i}$

 

 $z'=\left(-\dfrac{1}{2}+\mathrm{i}\dfrac{\sqrt{3}}{2}\right)z-\dfrac{\sqrt{3}}{2}+\dfrac{1}{2}\mathrm{i}$

$z'=\left(\dfrac{1}{2}-\mathrm{i}\dfrac{\sqrt{3}}{2}\right)z-\dfrac{\sqrt{3}}{2}-\dfrac{1}{2}\mathrm{i}$
