Numerical Analysis lec-4 Newton Raphson method

Hi, Today we'll learn about  Newton-Raphson Method  " Newton's Method ". this method is for finding successively better approximate solutions to the roots of a function (real valued). so are you ready for this............you will. Newton's Method: The Newton's method is one of the most powerful and well known method used for finding a root of f(X) = 0 there are many ways to derive Newton-Raphson method . the simplest way to derive this formula is by using the first two terms in the Taylor series expansion of the form.  Instead of working with the chord joining points on the graph of y= f(X) as in bisection method and false position method s. Newton's method uses the tangent at one point on the graph of y= f(X) therefor it requires only one instead of two initial guesses. Suppose X is an initial guesses draw the tangent line at X= X0 and procedure it to meet the X - axis at X = X1 Newton's Method which shows in picture above. now from righ

HTML - CSS lec-6 "TEXT"

Hi, today we'r going to learn about TEXT  "Headings and paragraphs  Bold, italic, emphasis  Structural and semantic markup". do you ready..............you will. HEADINGS -Structural markup: the elements that you can use to  describe both headings and paragraphs -Semantic markup: which provides extra information; such  as where emphasis is placed in a sentence, that something  you have written is a quotation (and who said it), the  meaning of acronyms, and so on write this code b/w <body> to </body> When creating a web page, you add tags  (known as markup) to the contents of the  page. These tags provide extra meaning  and allow browsers to show users the  appropriate structure for the page. HTML has six "levels" of  headings: <h1> is used for main headings <h2> is used for subheadings  If there are further sections  under the subheadings then the <h3> element is used, and so  on... Browsers display the contents

Computer Architecture lec-3 Computer System Organization

Hi, today we'll going to learn about  computer system organization & Processors so, are you ready for it.....................you will be. Computer System Organization A digital computer consists of an interconnected system of processors,  memories, and (I/O) input/output devices, This lecture is an introduction to these three  components and to their interconnection, as background for the detailed examination  of specific levels in the five succeeding lectures. Processors, memories, and (I/O)  input/output are key concepts and will be present at every level, so we'll start  our study of computer architecture by looking at all three in turn. Processors The organization of a simple bus-oriented computer is shown in Picture below. The  CPU (Central Processing Unit) is the ‘‘brain’’ of the computer. Its function is to  execute programs stored in the main memory by fetching their instructions, examining  them, and then executing them one after another. The components are 

HTML - CSS "Creating A Web Page"

Hi, today we'll learn about how to create a web page so let's begin, you have to follow my  each and every point. Creating a Web Page On Your PC To create your first web page on  a PC, start up Notepad. You can  find this by going to: 1-Start 2-All Programs (or Programs) 3-Accessories 4-Notepad You might also like to download  a free editor called Notepad++ . Type the code shown on the right Go to the File menu and select  Save as ... You will need to save  the file somewhere you can  remember. If you like, you could  create a folder.  Save this file as first-test. html Make sure that the Save  as type drop down has All Files   selected.  Start your web browser. Go to  the File menu and select Open .  Browse to the file that you just  created, select it and click on the   Open button. The result should  look something like the screen  shot below. If it doesn't look like this, find  the file you just created on your  computer and make sure that it  has

Software Engineering lec-2 About Software Engineering!

Hi, today we'll going to learn about Software requirements, specifications, applications and lots of more let's start with software engineering definition. Software Engineering -Software engineering is an engineering discipline that is concerned with all aspects of   software production form the early stages of system specification through to maintaining   the system after it has gone into use. -The economies of all developed nations are dependent on software. -More and more systems are software controlled software engineering is concerned with   theories, methods and tools for professional software development. -Expenditure on software represents a significant fraction of GNP in all developed countries. - Engineering discipline:  Using appropriate theories and methods to solve problems bearing in mind organizational   and financial constraints. - All aspects of software productions:  Not just technical process of development also project management and the develop

HTML - CSS lec-5 Structures (Elements and attributes)

Hi, today we'll learn about the elements and attributes used in HTML 5 so lets start from Elements: HTML uses Elements to describe the Structure of pages, lets look closer at the code from the last lecture, there are several different Elements. each Element has opening tag and a closing tag. Tags  tags act like containers. they tell you something about the information between their opening and closing tags. *The opening <html> tag indicates that anything between it and a closing </html> tag is HTML code. The <body> tag indicates that anything between it and the closing </body> tag should be shown inside the main browser window. Words between <h1> and </h1> are a main heading. A paragraph of text appears between these <p> and </p> tags. Words between <h2> and </h2> form a sub-heading. Here is another paragraph between opening <p> and closing </p> tags. Another sub-heading inside <h2&g
