 Welcome back to the session on latex. In this session, we will create our first latex document. But before we dive into typing, let us see some commands. We start our latex document by typing the document class, the syntax is slash document class article. Here, the article is the name of our document class. Some other classes are report, book, etc., which we will explore as we progress ahead. Usually, all documents have title, author and date. We write our title using the slash title command and we mention our title between the curly braces. Same is the case with the author and date. Here slash today represents today's date. We write our content in between slash begin document and slash end document. Let us see a demo. I am switching to text studio. So, let us write slash document class. As you type, you see there are some suggested options. So, I just print, press enter, document class I will mention as article. Then I will say slash begin document and I write my content. This is my first document in latex. This is the build and run option. So, we will build and view it. The pdf appears on the right side. So, pdf appears on the right side. So, my text has appeared. I have a page number. I am just zooming it for better readability. Now let us type some document information like title, latex, document, author, seruza and date. Sorry slash date slash today. Now let us build and run. What happened? My title author and date it is not visible in the document. What I am missing out is to tell latex to display these things. So, the command is slash make title build and run viola latex document by feroza and today's date. Now imagine what efforts would it have taken to create this in a simple text editor centering with appropriate space, the date, etcetera. Now let us save it. I am saving it. I have a folder called latex for students, engineers and scientists on my desktop, a folder called topic 1, a folder called session 3 and I will create a folder called code and I will save my document as session 3 in this folder. Now you must be wondering why am I doing all these things? Let us come to it. We again build and run. The output is same of course. Let us go to the folder latex for students, engineers and scientists, topic 1, session 3. Let us go to the code. If you see there are some other files also. You have your tech file which we ourselves wrote. You have your PDF file which got generated. But if you see there is something called as ox file, these are auxiliary files, log files and some other files as well. As of now we need not worry about these files or what do they mean? We can ignore them as of now. So we created our first latex document which looked like this. We also saw the use of slash make title command. So now you can create a basic latex document, build it and view it. I hope it was exciting for you to create your first latex document. Thank you. Have a nice day.
