1)((√2−i√2)(1−i√3)4)=((√2−√2√3)+i(√2∗(−√3)−√2)4)=((√2−√6)+i(−√6−√2)4)=(√2−√64+i(−√6−√2)4)
2)tgϕ=yx
3)tgϕ=−√6−√2√2−√6=(−√6−√2)(√2+√6)2−6=−(√6+√2)(√2+√6)−4=(√6+√2)24=6+2√12+24=8+2√124=8+4√34=2+√3
4)tgϕ=2+√3
5)ϕ=arctg(2+√3)
Are all agreed right?
If not - tell me where the error.
And yet, how to find arg z ???
