1
00:00:05,620 --> 00:00:16,110
The Toti ratio is Tangut of angle it is equal to the ratio of sight of the two accolade to site adjacent

2
00:00:16,150 --> 00:00:26,930
to angerly and it can be written as equal to busy upon be busy up on AB which is equal to perpendicular

3
00:00:26,930 --> 00:00:32,210
of one base and in short it is written as okay.

4
00:00:33,320 --> 00:00:36,850
The Fourth D ratio is danger of angle A.

5
00:00:37,100 --> 00:00:41,810
This is equal to the reciprocal of tangent off.

6
00:00:42,100 --> 00:00:42,610
OK.

7
00:00:42,740 --> 00:00:47,200
So cotangent of it is just the reciprocal of tangent of a.

8
00:00:47,840 --> 00:00:56,210
So this is equal to sideways isn't to angle A upon sight opposite to angle A which is equal to AB upon

9
00:00:56,210 --> 00:01:02,230
b c AB upon B C which is equal to based upon perpendicular.

10
00:01:02,780 --> 00:01:05,480
And in short it is written as Scott.

11
00:01:05,670 --> 00:01:10,020
Next the Fifth D ratio is second angle.

12
00:01:10,710 --> 00:01:19,590
It is equal to the reciprocal of course and that is cossie and it can be written as equal to the regime

13
00:01:19,590 --> 00:01:27,980
of hypothenuse to the side edges and 2 and B which is equal to is upon AB which is equal to hypothenuse

14
00:01:27,980 --> 00:01:33,080
up on base and which is equal to say OK.

15
00:01:33,490 --> 00:01:36,170
Sixth and the last ratio is off.

16
00:01:36,230 --> 00:01:46,300
And in it is equal to the rest Rogallo sign of angerly it is equal to the ratio of what news to the

17
00:01:46,300 --> 00:01:48,420
side opposite to angle.

18
00:01:48,980 --> 00:01:56,090
And this triangle it can be written as equal to see a born b c which is equal to hypotenuse upon the

19
00:01:56,100 --> 00:01:57,150
Ben Diggler.

20
00:01:57,350 --> 00:02:02,180
And in short it is written as cause acting as well.

21
00:02:02,360 --> 00:02:06,980
And I've shown that you should learn all these 60 ratio in this order.

22
00:02:08,150 --> 00:02:17,710
And to make it very easy it is very necessary to learn the definition of all these 60 ratios.

23
00:02:18,080 --> 00:02:21,930
OK I'm going to help you in the videos.

24
00:02:23,590 --> 00:02:29,730
To learn these results learn the important results in a faster manner.

25
00:02:29,960 --> 00:02:35,050
OK so time is required and more learning is done.
