[00:00:00]as a math teacher.

[00:00:01]>> Yeah.

[00:00:04]>> No, as a math teacher some of the topic like last day I did irrational. So that time my explanation is so like that.

[00:00:20]>> Okay. Tell me what is the value of time?

[00:00:27]>> Time is rational. No, you >> is irrational but is rational.

[00:00:36]>> You are wrong.

[00:00:40]>> Is approximately equal to >> ah approximate is different from >> equal.

[00:00:46]>> So what is irrational when you introduce first introduce pi and what is the value of pi? Everybody will answer 22.

[00:00:56]The other day was Friday. Which is Friday?

[00:01:00]>> March 14th.

[00:01:01]>> Why March 14th is Friday? What? Why March 14th is Friday?

[00:01:08]>> 3.14 that is an approximate. You look at pi day TPS you will see an explanation.

[00:01:14]So 3 March 14th we consider it as a pi day because it's an approximate value which we can realize.

[00:01:23]So what is that irrational? Some things cannot be divided by something and get a number. For example, you take one circle, identify the perimeter, get the perimeter, divide by the diameter, you will get the number.

[00:01:45]But 100 people do they get 100 different numbers.

[00:01:51]same number nobody can get so >> yeah that is what I'm saying >> yeah that number you will get I will get based on the best precision which I do everybody gets a different number which is not at all correct you understood but which is very close to some number which is not the exact number which you can divide and get it therefore that is named as part now you got an explanation of what is a rational number right >> something which cannot be measured something which cannot be determined but there is existing a number because I'm sure when you divide the perimeter by the diameter you will get some number 2 pi r that is how the formula is made okay who identified there is a kerala person who is identified this who is that person so many people did experiment a different part of the world in Trishua that's where my wife is from San Graham is the old name there is a scientist called Madam Sav identified or calculated the values similarly so many other people calculated values everybody got not exact Exactly 3.14.

[00:03:22]Close to 3.14.

[00:03:25]Nobody got 22x 7. Close to 22x7.

[00:03:29]You understood?

[00:03:31]The best meter you take, precision you take, measure it perfect then also it is not perfectly.

[00:03:38]Same equipment somebody else uses.

[00:03:40]Mathematics you cannot have errors.

[00:03:44]Mathematics is perfect. So then people call it as pi. So pi is like a concept.

[00:03:52]Pi is like a number which is given where number doesn't exist in the normal sense.

[00:04:00]That is why rational numbers are more common. Irrational rarely we use good question. Wonderful. And now I have explained you in an entirely different style which I never explained in my life.

[00:04:16]You understood?

[00:04:18]So each explanation which I give last 10 day what I spoke after that today only I'm thinking about Mr. P otherwise I never thought about but I have to speak something little better than that otherwise once asked critical thinking I will not be a critical thinking person I'm a scientist I'm a critical thinking person. So when I'm explaining today it will be different tomorrow when I talk about pi I'll talk entire will be different because I'm creative I have critical thinking I know my audience accordingly I'll speak that was a general talk on a now this is for teachers it will be
