Complex number || 11th Math || Chapter 1 Lec 2 #11thmath @a2zpractical991

Whenever you see two complex numbers appearing to be equal What do we have to do? We must equate its real part with the real part? square root of minus 16 plus 3 square root of minus 25 What is the value written for z2? C plus id Okay? Hello friends, how are you? I hope you are all doing great, must be doing great My name is Rahul Singh, and in our last lecture, we started discussing complex numbers. Today we continue with the next part of the same lecture. Today is our second lecture. If you haven't watched the first lecture First, watch the first lecture, then come here. Last lecture we saw What is a complex number, and the history of complex numbers And what are its real-world uses? Disconnecting the power supply from the device is recommended. I mentioned in the previous lecture whenever the real part and the imaginary part You combine with each other What do we call that number which is formed? What is a complex number, what is a complex number Whenever the real part and the imaginary part You combine with each other What do we call that number which is formed? complex number Also, let me give you an example here. How to write a complex number 3 plus i 4, this is your complex number If these numbers are also appearing like this This is also a complex number. What can I do? 3 plus or minus 4 I can write in this way And once again, into which form has this turned? Has turned into a plus IV form So whenever, whatever number If they were appearing in the form of A plus IV So, what do we call such a number? complex number Already mentioned in the previous lecture. Wherever the root of the forest may be If it's shown, then I have to write about it. On his bench, we sit ourselves down Well then, I'm off. This is our problem. I am writing this problem again. What is written? Root minus 16 Plus Three Root minus 25 Plus root up -36 Plus root up -625 What can I do? Avtan's Peha, the beloved mother, together with her, a compassionate soul, is the one who truly understands the essence of this matter. The river flows through the village every day, carrying the child's belongings. It feels exactly like a pinch of salt. I Do it Where when Anywhere root Mine One I'll show it to you His What is Jagap? To write I I Write Hi So where I Where Me root We have to write I in its place. So simply what should I write here I will write Plus 6 25 Into me I Any number with I I will multiply. So, what will be the root of up 16i? What is the square root of root 16? 4 is it So, what exactly do I write here? 4 into I And I will go to 4 I will go So what will happen? I will be 4. So what should I write? direct 4 I What does it write? There was also a small mistake here. What is here as well? It's minus. Sorry, friends, a small mistake occurred So we people What do we need to do now? So what do we have to do? Addition and subtraction need to be performed. What we people have I've been doing it since childhood addition and subtraction So we know What is 15 plus 4? 19 will be What will 96 be? Your 25 I will come And this is minus 25i When you people have both of these You will subtract. So, will the answer come out? Zero Eye Write zero or simply write zero So, this is the answer to your first question. Alright So we move forward. What should you pay attention to? wherever the root of minus 1 appears What should we write to him? I want to write simply You just need to pay attention to these things. That's how it should be solved. I made a small mistake here. This was the square root of minus 625. In his notebook, I had written "plus." Then, after that, I had a little problem. Why is this happening? that such answers were not coming out We are back again If you didn't understand that problem So we solve it again And carefully look What am I doing? What did I say? wherever the root of minus 1 appears What should we write to him? I want to write I'll see what I can write 4 times 4 x 16 16 x Write the name of the file into Root of nine into root of minus one Then minus 3 times root of 16 times root of minus one What should I say to you? Because wherever you see the root sub-minibus Lua, we have to write I there. So, wherever "Root Up Mibas Lua" appears, what should we write here? I want to write a poem I know, Dogo What is the root of four? It is going to be a success. If we take the square root of the square of four So what will happen? Too higha So I will simply write here two Okay I will write. I will write it. Jattu will be here shortly. If our gamble number is to be aligned with the devolved number for holders, then it has to be competitive. I already told you before breaking it. Listen carefully, look closely the number that is not associated with I We will say "Real Part" for that number. There doesn't seem to be any I with A. Look here, what was already told earlier The number not associated with I We will say "Real Part" for that number. So this is the boat. Look at this opera here. Which one is it, that is, the property of equality of complex numbers, namely, whenever two complex numbers are equal, their real parts must be equal to each other, and their imaginary parts must also be equal to each other. Property wants to say exactly what I've just told you all. Please pay close attention to what I've explained, make sure you've understood it correctly. If you don't understand, go back to the previous lesson and review these points again. And that's it. What does a complex number say about its imaginary part? The imaginary part of a complex number is the coefficient of the imaginary unit, and this is what you denote as b. Let's look at its sign. What is the sign plus me? So, what should we do to make it minus? Then, if we take its conjugate, what will we get? z equals, this plus me, so minus i minus b; that's all we need to do, just simply like this. With the help of Palmaran, the divine mother of Anuparti Such a person is truly a great soul. In the midst of chaos, the wise man brings peace and countless opportunities. Hello, welcome to the community. What is to be written Write those real parts with real parts. And the imaginary part is, write the imaginary part along with the imaginary part, and also write imaginary parts with imaginary parts Write the real parts in one bracket. This requires us to place the Indians in a bracket. Thike to kya ye, I B Plus I D And look here, I, what is it? Khaun is a man. If I'm not happy, we'll just take it out of the brackets. I can write it like this A plus C plus You must understand what I'm trying to say, right? So we move forward and look at some properties of addition, which are the properties we examine. You must understand what I'm trying to say, right?
