This question, we have to sketch the least positive angle theta and find the values of all 6thogrammetric functions of that terminal side, which ends on angle theta.
00:12
So in this case, why is negative root 6x plus y is negative root 6 plus y is zero where x is negative, where x is negative.
00:27
Clearly these are the two points where x is positive.
00:31
This is positive, this is positive.
00:33
So, a and d are clearly not possible.
00:36
So if x is negative, that's what we have to find.
00:38
So y is root 6, 6, that's how we can write by adding root 6 as both sides.
00:43
And it has a positive slope.
00:45
And a positive slope would mean that the line would be like this.
00:49
And since it is passing through the origin, because 0 ,0 satisfies it.
00:53
So this is how the rhine looks.
00:55
And for positive values of x, sorry, for negative values of x, this is where the vector will lie.
01:01
So this is the correct choice for this particular graph, which is graph b.
01:08
And then we talk about all the six trigonometric functions.
01:12
So in quadrant three, first off, only tan and only tan theta and cot theta is going to be, and cot theta are going to be positive, rest all or negative in quadrant three.
01:26
Now to find that...
