\(\displaystyle{ \frac{(-cos\frac{\pi}{6}+jcos\frac{\pi}{3})^{3}(1-j)^{14}}{(1+j)^{13}}}\)
mi wyszlo:
p. algebraiczna \(\displaystyle{ \frac{1}{1-j}}\)
p. tryg. \(\displaystyle{ \frac{\sqrt{2}}{2}(cos\frac{\pi}{4}+jsin\frac{\pi}{4})}\)
p. wyk. \(\displaystyle{ \frac{\sqrt{2}}{2}e^{j\frac{\pi}{4}}}\)
