Sagot :

The point (-2,2), we need to evaluate each case

In this case, for the real part we need to obtain -2

[tex]_{}2\sqrt[]{2}(\cos (\frac{3\pi}{4}))=-2[/tex]

For the imaginary part, we need to obtain 2

[tex]2\sqrt[]{2}(\sin (\frac{3\pi}{4}))=2[/tex]

As we can see the complex number that is shown in the graph is

[tex]2\sqrt[]{2}(\cos (\frac{3\pi}{4})+i\sin (\frac{3\pi}{4}))[/tex]
