Folosind scrierea sub forma trigonometrica se sa calculeze:
VA ROG MULT DE TOT

Answer 1

Răspuns:

$\frac{ \sqrt{2} }{2} \times ( \cos( \frac{13\pi}{12} ) + i \times \sin( \frac{13\pi}{12} ) )$

Explicație pas cu pas:

$\frac{ \sqrt{3} - i }{2i - 2}$

$\frac{2( \cos( \frac{11\pi}{6} ) + i \times \sin( \frac{11\pi}{6} )) }{2 \sqrt{2} \times ( \cos( \frac{3\pi}{4} ) + i \times \sin( \frac{3\pi}{4} ) ) }$

$\frac{2}{2 \sqrt{2} } \times ( \cos( \frac{11\pi}{6} - \frac{3\pi}{4} ) + i \times \sin( \frac{11\pi}{6} - \frac{3\pi}{4} ) )$

$\frac{ \sqrt{2} }{2} \times ( \cos( \frac{13\pi}{12} ) + i \times \sin( \frac{13\pi}{12} ) )$

greu, fi foarte atent la rezolvarea data de mine !!!!
