Here we have ourselves a lemniscape.
00:03
So the only, the way we know that is because it says r squared.
00:07
So for sign, we have r squared as equal to a squared sine of theta.
00:12
We're either going to be along the pi over four or along seven pi over four.
00:16
And the reason this happens is because if a is positive, sign has a maximum of pi over two.
00:22
When we bring in the two theta, so this should be two theta inside here, what we're going to do is condense everything by half.
00:28
So where it was pi over two, the maximum is now going to be at pi over four.
00:32
So this is positive.
00:33
So we're going to be along the theta equals pi over four.
00:36
So that's the orientation we have...
