Today we are starting a very interesting and a very easy subject for you which one code is

**MTH603 AND ITS NAME IS NUMARICAL ANALYSIS**

MTH603 SHORT LECTURES

For the word numerical we use at many places if you have done FSC if you have learnt physics and mathematics. You solved many numerical but now we are discussing about another branch of mathematics in which we discuss all the numerical and how to deal and how to understand it. In mathematics you also read out about derivatives, integration etc. these all the major part of numerical analysis.

**OVER VIEW**

Now we discuss about the introduction of this course.

** How we get this course?**

** Where we have to use it?**

**How to analyze all the problems with this course?**

**IMPORTANT NOTE:**

When you are preparing this course, you have a copy and a pencil to write out all the important topics of this course and important key points. You can use or apply this course on your computers we will discuss how to apply it.

#### MTH603 SHORT LECTURES

**Alternate names of this course**

**Numerical computation**

** Numerical methods**

But we use numerical analysis

And try to demonstrate this course. So that you have clear your concepts or build up a concept of this course.

**LECTURE 1**

**Three parts of this lecture Is**

**Introduction**

**Number system**

** We are discussing about the examples of this question**

**INTRODUCTION**

**So let’s start a number one introduction.**

In this Chapter we discuss about the some concept of representation of numbers on computers and some errors which are introduced during competition and after that problem solving using computer and the step in more than also discussed in briefly . MTH603 SHORT LECTURES

**Number system**

Number system in our daily life also use number system

For example there is some number system in our life like

binary system in which we use two numbers 1 and 0.

Than octal system and its base number is 8

Decimals number system it’s base is 10

Hexadecimal number system and in its base is 16

Orbital real number can be written in number systems are given so we can discuss it later .

Electronic computers used binary system whose base is two symbols used in the system are zero and one which are called binary digits. The internal representation of and that with the computer is in binary form. MTH603 SHORT LECTURES.

**EXAMPLES**

I am giving you some example of all these number systems so you have to read out very carefully.
