Q: Expresseu en forma polar: $$-2+i$$
- $$2,236_{-26,565^\circ}$$
- $$2,236_{153,435^\circ}$$
- $$2,236_{-63,435^\circ}$$
- $$1,732_{-63,435^\circ}$$
- $$1,732_{153,435^\circ}$$
- $$1,732_{-26,565^\circ}$$
A: $$2,236_{153,435^\circ}$$ / $$1,732_{-26,565^\circ}$$
If partly right: 1

- $$0$$
- $$1$$
- $$i$$
- $$-1$$
- $$-i$$
- $$i^2$$
A: $$-i$$
