We are going to graph a polar coordinate, and the polar coordinate we're going to graph is 2, 5 pi, 4 radiance.
00:12
So r equals 2, and that means we're interested in the second circle that we see on the polar graph.
00:21
The first circle we see that has an r value of 1, and this has an r value of 2, so we're interested in that.
00:29
Now, theta is in radiance, and it's 5 pi over 4.
00:38
Now, looking at the labeled radiant measures, we don't see 5 pi over 4, but we can figure it out.
00:47
So i hope you like fractions.
00:52
Pi over 2 is over here, and if we take half of pi over 2, we'll get pi over 4.
01:04
Our coordinate has five pi over fours.
01:13
So half of pi over two, that is halfway to 90 degrees.
01:23
That's 45 degrees.
01:27
So 45 degrees should be, well, let's count these boxes.
01:35
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12.
01:42
And we want half of pi over 2.
01:45
So we want 6 boxes.
01:48
1, 2, 3, 4, 5, 6.
01:52
So this is pi over 4.
01:57
And we want 5 of these...
