Okay, what we want to go ahead and do is we want to plot this rectangular point in the rectangular coordinate system.
00:12
So the point is the square root of 7, comma, the negative square root of 7.
00:18
And so square root of the 7 is somewhere between the square root of 4 and the square root of 3.
00:25
So in between two and or square root of nine is in between two and three it is closer to the square root of nine than the square root of four so it's a little bit closer or above two and a half so if this is let's see we go one two three one so a little bit right here.
01:05
So about 2 .6 comma negative 2 .6.
01:09
So that puts it right down here.
01:11
So here is that point in the coordinate plane.
01:16
And remember in the rectangular coordinate system, this is a unique point, but in the polar coordinate system, it is not represented by a unique point.
01:26
And so we want two points in the polar coordinate system that would represent this point...
