[00:01:39]Oh, minus sin x by cos x equal to 1 Jagger is your sec x minus tan x with x equal to 4 theta equal to the three 4 theta equal to x equal to 4 theta equal to 1 by the answer already 4 days ago Question number two would you 4 tan theta plus 3 cot >> [clears throat] >> But if what is square Today I made a 6 or square go to put on my head at 16 tan square theta plus 9 cot square theta plus 2 a b 2 hello a hello 4 tan theta I'll be a lot 3 cot theta equal to 36 Hmm.

[00:03:06]That equal to 12.

[00:03:18]cot alpha plus beta 1 to 1 1 1 to cot beta cot beta minus cot beta to 1 cot sorry cot alpha minus minus plus alpha cot alpha into cot beta is equal to two.

[00:03:59]A cot alpha of cot of the success of the nation.

[00:04:06]A lucky a cot cot alpha into cot beta formula of support of my cot alpha plus cot beta.

[00:04:19]Cot alpha into cot beta minus one is equal to cot alpha plus cot beta.

[00:04:35]Into cot beta minus one by cot alpha plus cot beta is equal to one.

[00:04:51]Cot alpha plus beta of formula of cot A plus B of formula.

[00:05:07]45 minute of sorry 80 by 4 30 minute of pi pi by 4.

[00:05:13]The number clear.

[00:05:15]10 number.

[00:05:17]10 number question be simple question to it tan P they each tan money we need to P by B money P money perpendicular B money base money 2 XY by X square minus Y square ditch.

[00:05:40]Plus B.

[00:05:44]Pythagoras theorem.

[00:05:46]So P holds a 2 XY.

[00:05:48]So 2 XY the square. xy.

[00:05:51]So, 2 xy the square.

[00:05:53]B whole to x the square minus y square square square root.

[00:05:59]So, 2 xy square say 4 x square y square.

[00:06:04]Oh, x square minus y square a minus b whole square x square square x 4 x to the power 4.

[00:06:10]Plus y to the power 4 minus 2 a b.

[00:06:13]2 x square y square.

[00:06:16]The square root of that.

[00:06:18]So, a a we give it plus or minus. Then I'm going to a a give it.

[00:06:24]x to the power 4 plus y to the power 4.

[00:06:27]Plus.

[00:06:28]2 x square y square. I don't square root to my data x square plus y square square root of that.

[00:06:35]You have like I say x to the power 4 y to the power 4 plus 2 x square r square.

[00:06:39]I don't plus a whole to x square y square. x by a limit.

[00:06:44]You have a part of something.

[00:06:46]It is the each.

[00:06:48]Sine square P into cosec P I can write 1 by sine P.

[00:06:53]So, sine P 100 to you. So, I'm going to answer you.

[00:06:56]Sine P or sine P whole to P by H. So, P I already done it. 2 xy.

[00:07:04]Oh, H already done it.

[00:07:08]x square y square. Answer [clears throat] A option A.

[00:07:13]Hello.

[00:07:14]Answer number question for the whole state I'm going to go.

[00:07:19]The sine. 25 sine A is equal to 7.

[00:07:24]The sine A is equal to 7 by.

[00:07:28]25.

[00:07:30]So, I mean I don't sine whole to P by H.

[00:07:33]So, P by H the amount 7 by 25.

[00:07:39]Then I'm going to B B whole to amount H the square minus P the square the square root.

[00:07:45]I'm going to do this as you all What you saw square on Saturday and check the playlist of this.

[00:07:50]So it's baby the percentage of 7 sign A minus 2 cos A by tan A.

[00:08:02]So if you have value put it to give up.

[00:08:04]7 into sign which is P by H.

[00:08:06][clears throat] So P by H money P or just have to I'll eat so cheap 20.

[00:08:14]Cos A or just B by both of these are going to pass three things up. The B by H or just cos P by So 2 cos A cos A that they do.

[00:08:25]>> [clears throat] >> Cos of B by H and B get the hell out of 20. 20 20 20 tan A or the tan A to me something to be Johnny check B by B. B by B money P A you tell me what P or just have to be you would say 20.

[00:08:42]20 1 just by 4 to see Allah minus 4 to see by 4 to see Allah.

[00:08:48]So let you touch 7 by 20 that's 20 by 7 Allah.

[00:08:53]The one by 4 to see into 20 by 7 and 20 by 7 4 to 7.

[00:09:04]4 to 7 7 4 to 7 20 answer that A.

[00:09:08]I have the quota correct number 20. The first check for that is the 8 common character.

[00:09:15]The cos x square theta minus cos square theta is equal to 8 over. So check over the element check over to 8 over 9. Hello I might leak only. The 8 8 into 1 8 number cos x square theta minus cos x square theta 1. I take it second try to get.

[00:09:33]Second [cough and clears throat] Allah 4 into cos square 60. Cos 60 or just 1 by 2. So, 1 by 2 squared.

[00:09:40]Plus three tan tan squared 30 tan 30 is root 1 by root 3. So, 1 by root 3 squared means 1 by 3 is equal to But you have to try into 1 by 4 plus three into 1 by 3. Three three four four two us.

[00:10:02]The one minus x squared theta is equal to Now, one that I'm looking at right here.

[00:10:13]x squared theta minus tan squared theta Okay, already with x squared theta which is I'll get tan squared theta B.

[00:10:21]What's it? I'm going to do one that I'm looking at right here.

[00:10:24]The tan tan x x theta The eight of you zero to the eight of you correct the data which I'm going to answer that you will see what I need to do. Hello, check me go to see.

[00:10:34]Sine 30 which is 1 by 2. 1 by 2 cubed which is 1 by 8.

[00:10:38]4 into sine 30 which is 1 by 2. The year of the one year of the two three years possible to the bully.

[00:10:46]Correct?

[00:10:47]After number of the easy question can I measure it A plus B value of okay for you.

[00:10:54]root 3 by 2 root 3 by 2 which is sine 60. The number A plus B is 60.

[00:11:04]30 sine A minus B 30 sine A minus B 30 1 by 2. The 1 by 2 which is sine 30.

[00:11:12]The A minus B number 30 I'm going to get the A 30 for you can I A plus B 30 60 Oh, A minus B 30 I have to B B cancel.

[00:11:26]The 2 A is equal to 90. The A number 100 degree The B plus C get the triangle to be good to A number money 180 minus 120 C equal to 135 D.

[00:11:47]Correct.

[00:12:02]Money sign plus sign 90 1.

[00:12:08]Oh, 690 BML. One. The one plus one I'm going to close.

[00:12:24]36 90 degree.

[00:12:26]Plus. Classic.

[00:12:30]3690 degree plus 31 power 36 52 1 power 36 sign 91 classic 90 B1. The one plus one number two.

[00:12:45]No number and I'm already.

[00:12:52]6 10 feet up.

[00:12:54]Is equal to classic.

[00:12:57]Plus 46 days.

[00:12:59]I'm a sick woman called classic corner.

[00:13:04]The classic burrito.

[00:13:06]I live for the 90 minus 30 audio.

[00:13:10]My 90 minus 10 feet up.

[00:13:12]The classic the 70 kind of auto classic ladies.

[00:13:17]The classic classic yellow.

[00:13:21]I'm going to angle angle someone else.

[00:13:25]I'm going to keep 90 minus 10 feet up is equal to 3 10 theta is equal to theta plus 46.

[00:13:33]The 10 theta type of actually is your 11 theta. A 46 type of actually minus 80 44 is your The theta is 4 degree. So I'm going to keep that in the 4 degree answer.

[00:13:47]The same number the simple question that I don't have to worry about.

[00:13:50]1 minus sine A gives you I'm going to go by sec A 1 by cos A cos plus tan A could be I'm going to sine A by cos A cos That part of it is 1 by sine A and T.

[00:14:08]Oh, it could be 1 plus sine A.

[00:14:12]by cos Maybe I'm going to A plus B into A minus B B So you use 1 minus sine squared All of them are as usual cos A only.

[00:14:24]The 1 minus sine squared equal to I'm going to say cos squared A only.

[00:14:28]The total cos A squared and 40 cos A cos A cos A cos A cos A cos A cos What is the question we ask you?

[00:14:39]It is very easy to The cosec 58 I'm going to change cos sec complementary 58 or 90 minus 80 32 is you And I'm 90 minus 58 or 32. The angle of complementary cos cos cos It is cos 32 cos So I'm going to cos 56 cos cos cos cos cos cos cos cos cos cos cos cos cos cos cos cos cos cos cos cos cos cos cos cos cos cos cos The cosec 34 sec into cos 1 sine into cosec 1 The answer is 2.

[00:17:17]>> Okay.

[00:17:18]Okay.

[00:17:20]Okay.

[00:17:21]Okay.

[00:19:07]Okay.

[00:19:10]Okay.

[00:19:12]Okay.

[00:19:13]Okay. which are all over the whole square over. I can simply take a poly right here I'm going to 2 sec 8 and 8. I am a fool 1 + 6 record level. So I get the usual answer to make it clear.

[00:19:25]A 1 second day.

[00:19:27]I'm a sec square A minus tan square A pocket clear.

[00:19:31]Close tan square A taco watch C 2 tan square root C.

[00:19:34]Plus 2 sec A into tan A watch.

[00:19:39]The 88 data for my plus card delay and it is also sec square A plus tan square A plus 2 sec A into tan A.

[00:19:52]So what can I make cool whole square for liquid A square plus B square plus 2 AB.

[00:19:57]I leave sec A the option of the quality for the alarm circle.

[00:20:03]Clear.

[00:20:05]So last question it will be so hard a question that I'm going to be put a square for the number.

[00:20:11]tan A plus cot A is equal to 2 days.

[00:20:16]I don't know what the photo square for those here.

[00:20:22]The tan square A plus plus cot square A into 2 tan A into [clears throat] cot A is equal. You put it for a sealer.

[00:20:38]I don't have 2 tan A into cot it to 1 easy way to generate it.

[00:20:42]The 2 into 1 2 is equal. But tan square A is what you I call my liquid area.

[00:20:49]sec minus tan whole chain though tan square A by sec convert for the 2 sec minus tan.

[00:21:00]So 88 is equal sec square A minus 1.

[00:21:04]Same thing.

[00:21:06]cot square will be a minute or something.

[00:21:09]See for could be America the same thing.

[00:21:12]Same format trick this cosec minus cot cosec identity cosec square A minus one plus two connected to one unit I'm going to press minus one.

[00:21:28]minus one plus two minus one The answer is four.

[00:21:33]sec square A plus cosec square A is equal to four.

[00:21:39]But here is the question I did. So I completely trigonometry fundamental playlist to me completely mathematics by you.

[00:21:47]I like you more for the answer I 687 order 247 paid up in order of WhatsApp number >> [snorts] >> to you Telegram number to you to you.

[00:21:55]Then I have to go to chapter two or three chapter two or three chapter two or three chapter two or three chapter two or three chapter two or three chapter two or three chapter
