Hi, i'm david and i'm here to have you on seeing your question.
00:03
In the question here we need to find the primary trigonometric ratios for each angle.
00:08
Now let me formulating the table to make it easier.
00:13
Here we will have 1, 2, 3, and here we will have 4.
00:30
And this will be the angle on the side, this will be the cosine, and this will be the tension on the x.
00:39
And here we will have the first angle we have the option a that will be the minus 5 out of 2.
00:48
And then if we want to find the side of the minus 5 out of 2, then we get this value equal to the minus 1.
00:58
Coside with the minus 5 out of 2, it will equal to the 0, tension of the minus 5 out of 2, to tension between the sine, defend the cosine.
01:10
So minus 1 divide 0 will be does not exist.
01:15
So it will be undefined here.
01:18
It will be undefined...
