 I got that. Yes sir? Yes sir, I got that. This X squared by AC is C squared plus A squared by 2 AC. AC is... You're telling me that you're not going to do this sir? No. Then it's... One minute. One minute. One minute. One minute. One minute. One minute. One minute. You're telling me that you're not going to do this sir? No. That's it. See, in this projection, projection means shadow. It's like when your head is a pot. In a similar way, it functions straight away, so that you can... Sir, can you do some trigonometry? Anything? Can you do two problems then? I can... Is there isn't three? Yes. Three? Yes. No. What's the difference? What is God's Satan? What is God's Satan? What is God's... God's... What is God's God's... What is God's... What is God's... What is God's... What is God's... What is God's... What is God's... No, that's not it. Okay, fine... Okay? Sir, if you look at the thing... Shhh! It's wonderful. So you have Cos R pipe from our summation of Cos... Sir, one question. Do you have something like an R? No sir. It makes a difference. Why? Yeah, it makes a difference. What do you get from that? I'm so sorry. Sir, instead of doing this, if you directly do it here... If you directly do it here... Then you go minus one. Now see it. The benefit of... Now one. Plus one, minus one. Plus one. So this term you say... The last term. Plus two. So instead of doing all this, if you substitute it here... Then you get the answer. But it's not positive. Shhh! So what is a positive? I'm buying out the rule, right? I feel it. What is your subscription? Yeah, that's right there. What do you get from that? You don't get paid. You don't get paid. See? Okay. So, how much is it? Signature? Signature, please. Signature. Signature. Signature. Signature. Signature. Signature. No, no, I'm not substituting. You notice that this becomes equal to this, this becomes equal to this, this is exact part of the text. And then all this becomes a part of the text. So, when you write it down in pairs of three like that, this you can write it down. So, now if this is exact part of the text, there will be three. So, each value will be one by eight, because this is star. It can cost equally. So, you get this equal to this, this equal to this, this equal to this. So, all this will be minus half. So, it will be costing minus half that the minus one by eight. And now, four times it's going to be minus four by eight. And then four will be plus one, minus one, plus one, plus one, minus one, plus one, minus one. That's it. This is minus half, two by eight. Cost you minus one by eight. Now, it's exact. When you go like this, like this, like this. There are only ten. Now the ten are cost ten by eight. Cost you ten by eight. This is equal. That's it.
