Converting rectangular coordinates to polar coordinates, what we have here is rectangular coordinates, negative 1, negative 3.
00:10
Negative 1 is our x and negative 3 is the y coordinate.
00:18
And we're going to first plot this point.
00:22
So negative 1 will go over 1 to the left and then down negative radical 3, which is a little bit less than 2.
00:32
Okay.
00:33
So, so, so there is our coordinate, which is in quadrant 3.
00:38
And we'll use this a little bit later to determine our theta.
00:43
So next we're going to determine the r.
00:47
First let's note that this is the form that a polar coordinate has, r theta.
00:56
So to find the r, we're going to use the expression square root of x squared.
01:04
Plus y squared.
01:07
This will actually give us the distance from the origin to that point.
01:14
So in our example, we're going to have the square root of a negative one squared plus the square root of a negative three.
01:28
Oh, i'm so sorry.
01:31
That should be the negative square root of 3 squared.
01:40
So let's try that again.
01:43
Negative square root of 3 squared.
01:47
So negative 1 squared is just 1...
