All right, looks like we're just redoing this, but this time we want the magnitude to be zero of the result.
00:10
So last time it was 600, but we want it to be zero.
00:16
Therefore, everywhere that it says 600, i'm going to have to change that to zero.
00:24
Negative f to y, well, if 600 minus, f2y was 401, well then this would have been $199, because $600 minus $199 is 401.
00:46
Okay, so that means that f3y changes, which is going to change this.
00:53
So let me put this into a calculator.
01:00
F3y is just going to...
01:07
Be, let me think here.
01:35
Let me think about this some more.
01:36
F3y.
01:37
I want to think about f3y.
01:41
F3y, is the opposite of f2y, and f2y is f22, cosine 30, cosine 40.
01:57
So f2 is 300, cosine 30, cosine 40...
