We will now determine the sine cosine and tangent ratio of this angle 2100 degree.
00:07
So first let's understand in which quadrant this angle lies in or in other words, we will also find the reference angle corresponding to this 2 ,100 degree.
00:18
So first i'm going to go around all these four quadrants.
00:22
If i go around this once i'm reaching this 360 degree.
00:27
So i should go further.
00:28
That is i go around this one more time so if i make two complete revolutions i will be reaching the 720 degree and likewise i go around this three times i'll be reaching 180 degree four times i'll be reaching 440 degree 5 times i'll be reaching 1 ,800 degree and here i am just a shot of 300 degree to reach this 2 ,100 degree that is is 1 ,800 plus 3 ,000 equals 2 ,100 degree.
01:03
So this when i utilize this fifth cycle, i can write down this 2 ,100 degree as 1 ,800 plus 300 degree.
01:14
That is, i can write down this as 5 times of 360 degree plus 300 degree.
01:23
In other words, the angle is going to be the same as this 2 ,000.
01:28
Is going to be the same as the 300 degree.
01:31
But in this case, so we are not getting the reference angle because it is more than 90 degree.
01:36
So we can also use this or instead we go around this six times...
