Assignment # 1
Section In charge: Husna Muzaffar Total Marks 20
Instructions

To solve this assignment you need to have a good grip on lectures 1-15. The course is segmented into four sections, each of which is supervised by a different faculty member. Information regarding the section in charge can be
found in the course information section on the LMS. A distinct assignment file has been given to each section, resulting in a total
of four separate assignment files. The relevant assignment file can be downloaded from the announcement section of the course. It is important to note that students can only view the announcements relevant to their respective sections. You will prepare the solution of assignment on Word file and upload at the assignment interface on LMS as per usual practice. Plagiarism in the submitted assignment will lead to a zero grade. Additionally, any student who submits a solution file that is not applicable to their section will also get a zero grade.

• ### MTH603 Grand Quiz Solution and Discussion

@zaasmi said in MTH603 Grand Quiz Solution and Discussion:

A series 16+8+4+2+1 is replaced by the series 16+8+4+2, then it is called

Each number in the sequence is half the value of the number receding it. So the common difference in the series is dividing by two.

16รท2=8

8รท2=4

4รท2=2

2รท2=1

1รท2=ยฝ

The answer is ยฝ or 0.5

When you keep dividing by two, you will notice an interesting pattern: the denominator continues to increase by two, while the numerator value remains the same. Thatโs fascinating because in natural, whole numbers the numbers in the series would decrease by two.

1/4 , 1/8 , 1/16 etc.

• ### decimal fractions

@engr-ali said in decimal fractions:

Assallamulikum Sir, Conversion (59)10 into binary 59/2=28-1 ? 28/2=14-0 14/2=7-0 7/2=3-1 3/2=1-1 (111001) ?

Dear @Engr-Ali ,

\$(59){10} = (111011){2}\$

The mistake you have made is in the first step where you divided \$59/2\$. It has to be \$29-1\$ instead of \$28-1\$.

• ### Errors in Computations.

@vu-kick said in Errors in Computations.:

What is synchronous and asynchronous and what are there applications in real world. Which applications use this sort of techniques.

The word synchronous and asynchronous are very general terms that are used in different fiels representing different phenonena. If you can please ask it more clearly that in what context you are asking. It will be good if you please mention what page of handouts, what slide of ppts or where in the lecture video of the numerical analysis you studied/heard about it. Then weโll be able to explain it well.

• ### Solution of Non Linear Equations (Bisection Method)

@oxama-malik said in Solution of Non Linear Equations (Bisection Method):

respected sir, sir ma na ye pochna tha ka regula falsi method ma hum ye bhi formula use kar sakta hai. please guide kar dya. the first approximation solution x1 is given by X1=(a(f(b))-b(f(a))/f(b)-f(a)

That is right. You can use this formula.

In fact, the formula given in the handouts becomes same after you simplify it. Also \$x_{n-1}\$ will become \$a\$ and \$x_{n}\$ will become \$b\$.

So use any from the two formulas you find easier.

• ### replace the part of curve between the points

@engr-ali said in replace the part of curve between the points:

AoA, Sir if you may plz explain โreplace the part of curve between the points A(x_n, f(x_n)) and B(x_n-1, f(x_n-1)) by a chord in the intervalโ . diagrammatic explanation will be a great help in comprehension of the subject matter. Thanks

A chord is basically a straight line by joining two points of a curve or circle. The root of a equation means that when we give input value x then the functional value of that input will be zero then x is called the root of that equation. We take the two points of the interval on the chord instead of the curve shape because the value of root lies in that interval and this mean this value will lie on x-axis and if this is the root then functional value will be zero and we know that y-axis (functional value) is zero at x-axis.
