Here we're supposed to write these in trig form.
00:05
So this 2 minus 2i, that's 2 this way, and 2 that way.
00:15
So this is our actual vector from here to there.
00:22
Like i said, this is 2, that's negative 2.
00:26
And if that is the case where these two values are the same, well, then i know that that angle there is a 4i3 angle, but it's going down so it's actually negative 45, or pi over 4 and that's the same as this angle would be 7 pi over 4 now then we have to figure out what's the hypotenuse of this go from there there that's 2 and that's 2 to find the hypotenuse 2 squared plus 2 squared that's 4 plus 4 is 8 so the square of 8 is the hypotenuse or 2 squared with 2 so to write in the trait form you would have 2 squared two times plus a pi sign.
01:21
7 pi over four.
01:28
Next one, you have one minus i.
01:31
Same thing.
01:33
Going to the right one and down.
01:41
So the vector is actually this one...
