[01:00:30]Second, >> 60 42° right?

[01:00:38]>> Yes sir.

[01:00:39]>> 20 times, sir?

[01:00:41]>> 60.

[01:00:43]>> How many times?

[01:00:45]>> 4 20 16 45 times, right?

[01:00:51]>> Yes.

[01:00:52]>> Sir, it is 180.

[01:00:57]>> 180.

[01:00:58]>> Okay, sir. Okay. 180 180.

[01:01:01]>> Yes sir.

[01:01:02]>> 45 times.

[01:01:03]>> Yeah. 45° 135° >> 135° >> * 30 * 3 * 45 into 7 35° Right.

[01:01:34]>> Yes.

[01:01:38]>> Is it clear?

[01:01:39]>> Yes, sir.

[01:01:40]>> Yes.

[01:01:41]>> Later you can do it.

[01:01:43]>> Okay.

[01:01:46]>> 10,000 to this 310,000 >> 3 into 90 + 30.

[01:02:02]is equals to >> okay you can do it later >> okay >> okay sir >> sir okay yourself please later you can do Right. Next problem.

[01:02:36]and triangle ABC + B by 2 into a + b by 2 into tan c2= first option sin 2 Okay. Second option one.

[01:03:08]Third option 2 A.

[01:03:11]Fourth option B.

[01:03:17]Yes, please.

[01:03:21]What is A + B plus? A + B +al.

[01:03:30]What is A + B?

[01:03:34]180 - 180US 3 >> A + B / 2 is >> 180 - C by 2, right?

[01:03:45]>> Yes, sir. Yes, sir. B2 is equal to 90us C >> 90us C by 2, right?

[01:03:54]>> Yes, sir. Yes, sir.

[01:03:57]>> We want what? We want tan of A + B / 2, right?

[01:04:00]>> Yes, sir. Okay.

[01:04:04]tan a + b by 2 = tanus by 2 >> this is equal to 1 into 90 1 quadrant all are positive right >> yes it is 1 into 90 is odd number means c by 2 right yes B2 by 2 A + B by 2 = C by2 right?

[01:04:39]>> Yes sir.

[01:04:39]>> Yes sir.

[01:04:40]>> Yes sir.

[01:04:41]>> Therefore tan of A + B / 2 into tan C by 2 equal to C by 2 into tan C by2 right?

[01:04:52]>> Yes sir.

[01:04:53]>> Yes sir.

[01:04:56]>> C and tan are what? Transal or not?

[01:04:59]Yes sir sir question their product is equal to one right?

[01:05:06]>> Yes sir.

[01:05:07]>> Answer is >> C by2 consider as theta co theta equal to 1 by tan theta tan theta tan theta gets cancelled right?

[01:05:14]>> Yes sir.

[01:05:16]>> Tan and quarter angle is same C by2 C by2 same angle or not?

[01:05:20]>> Yes sir.

[01:05:20]>> Yes sir. Same angle.

[01:05:22]>> Therefore tan theta into the equal to what? One >> one.

[01:05:27]>> Yes.

[01:05:30]Yes, sir.

[01:05:30]>> Right.

[01:05:34]>> Okay.

[01:05:40]Okay. This I will post one worksheet to try those problems.

[01:05:44]Okay.

[01:05:45]>> Okay, sir.

[01:05:46]>> Monday test is postponed. I will tell you later.

[01:05:51]Okay, sir.

[01:06:01]I'll be >> right.

[01:06:05]>> Okay.

[01:06:06]>> I will I will put one worksheet. You try it. Try those problems.

[01:06:10]>> Okay sir. Okay sir.

[01:06:13]>> Bye. Okay.

[01:06:14]>> Bye.

[01:06:16]>> Thank you.

[01:06:18]>> Thank you sir.

[01:06:20]>> Thank you sir.

[01:06:22]>> Right.
