INTRODUCTION
The purpose of add math project work is to provide an opportunity for
students to apply mathematical concepts and skills in problem-solving that they
have learnt in classroom. This project work can help students to understand add
math more easily and aid students in visualising certain mathematical concepts
which
are
difficult
to
show
clearly
through
pen
and
paper
In addition, this project work is essential to help students to learn how to cope
with future challenges using their mathematical abilities. It also aims to foster
moral
values
in
line
with
a
student's
academic
development.
besides this, the students are encouraged to do their own research. As a result
students become more independent. It also makes the learning process more fun
and
effective.
This project work also makes add math an enjoyable and exciting subject
encouraging the students to learn math more skills in more heuristic manner.
Therefore it is beneficial to all students who take add math

History of differentiation
The concept of a derivative in the sense of a tangent line is a very old one, familiar to Greek geometers such as Euclid (c. 300 BC), Archimedes (c. 287–212 BC) and Apollonius of Perga (c. 262–190 BC).[1] Archimedes also introduced the use of infinitesimals, although these were primarily used to study areas and volumes rather than derivatives and tangents; see Archimedes' use of infinitesimals.
The use of infinitesimals to study rates of change can be found in Indian mathematics, perhaps as early as 500 AD, when the astronomer and mathematician Aryabhata (476–550) used infinitesimals to study the motion of the moon.[2] The use of infinitesimals to compute rates of change was developed significantly by Bhāskara II (1114–1185); indeed, it has been argued[3] that many of the key notions of differential calculus can be found in his work, such as "Rolle's theorem".[4] The Persian mathematician, Sharaf al-Dīn al-Tūsī (1135–1213), was the first to discover the derivative of cubic polynomials, an important result in differential calculus;[5] his
Treatise on Equations developed concepts related to differential calculus, such as the derivative
function and the maxima and minima of curves, in order to solve cubic equations which may not have positive solutions.[6]
The modern development of calculus is usually credited to Isaac Newton (1643–1727) and Gottfried Leibniz (1646–1716), who provided independent[7] and unified approaches to differentiation and derivatives. The key insight, however, that earned them this credit, was the fundamental theorem of calculus relating differentiation and integration: this rendered obsolete most previous methods for computing areas and volumes,[8] which had not been significantly extended since the time of Ibn al-Haytham (Alhazen).[9] For their ideas on derivatives, both Newton and Leibniz built on significant earlier work by mathematicians such as Isaac Barrow (1630–1677), René Descartes (1596–1650), Christiaan Huygens (1629–1695), Blaise Pascal (1623–1662) and John Wallis (1616–1703). Isaac Barrow is generally given credit for the early development of the derivative.[10] Nevertheless, Newton and Leibniz remain key figures in the history of differentiation, not least because Newton was the first to apply differentiation to theoretical physics, while Leibniz systematically developed much of the notation still used today. Since the 17th century many mathematicians have contributed to the theory of differentiation. In the 19th century, calculus was put on a much more rigorous footing by mathematicians such as Augustin Louis Cauchy (1789–1857), Bernhard Riemann (1826–1866), and Karl Weierstrass (1815–1897). It was also during this period that the differentiation was generalized to Euclidean space and the complex plane.

History of arithmetic progression
Euler stated that every arithmetic progression beginning with 1 contains an infinite number of primes. The theorem in the above form was first conjectured by Legendre in his attempted unsuccessful proofs of quadratic reciprocity and proved by Dirichlet in (Dirichlet 1837) with Dirichlet L-series. The proof is modeled on Euler's earlier work relating the Riemann zeta function to the distribution of primes. The theorem represents the beginning of rigorous analytic number theory.
In mathematics, an arithmetic progression (AP) or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant. For instance, the sequence 3, 5, 7, 9, 11, 13, … is an arithmetic progression with common difference of 2.
If the initial term of an arithmetic progression is and the common difference of successive members is d, then the nth term of the sequence is given by:
and in general
A finite portion of an arithmetic progression is called a finite arithmetic progression and sometimes just called an arithmetic progression. The sum of a finite arithmetic progression is called an arithmetic series.
The behavior of the arithmetic progression depends on the common difference d. If the common difference is:
Positive, the members (terms) will grow towards positive infinity.
9
Sum
This section is about Finite arithmetic series. For Infinite arithmetic series, see Infinite arithmetic series.
The sum of the members of a finite arithmetic progression is called an arithmetic series. Expressing the arithmetic series in two different ways:
Adding both sides of the two equations, all terms involving d cancel: Dividing both sides by 2 produces a common form of the equation:
An alternate form results from re-inserting the substitution: :
In 499 AD Aryabhata, a prominent mathematician-astronomer from the classical age of Indian mathematics and Indian astronomy, gave this method in the Aryabhatiya (section 2.18) .[1]
So, for example, the sum of the terms of the arithmetic progression given by an = 3 + (n-1)(5) up
10
Product
The product of the members of a finite arithmetic progression with an initial element a1, common
differences d, and n elements in total is determined in a closed expression
where denotes the rising factorial and denotes the Gamma function. (Note however that the formula is not valid when is a negative integer or zero.)
This is a generalization from the fact that the product of the progression is given by the factorial and that the product
for positive integers and is given by
Taking the example from above, the product of the terms of the arithmetic progression given by

TASK 1
The problem of sufficient water supply has become a main issue among
the countries around the world. Proper planning is very important to make
sure the water supply is sufficient. Carry out a simple study to solve the
problem. You are suggested to use various resources such as internet,
printed materials, ground study and others. Discuss on how additional
mathematics can be used to solve the problem.
For this coursework, I have carried out a study on water supply problem in the district inconclusive. Total of 1000 respondents villagers set. The following are water supply problems that occurred in the district Machang
17
I've been using the knowledge of Additional Mathematics to solve the problems
on the water needs.
Problem: The size of a small tank
Methods: Differentiation
If the volume of the tank to be constructed is 50 m3.
Minimum surface area required to build the tank was calculated using the
'differentiation'
18
20
Task 2
You are assigned as an engineer of a construction firm. You are
responsible to buld an enclosed water tank for a housing estate which
consist of 60 houses. The rate of water entering every house is different
and the rates are 1000cm
3min
-1for the first house , 990 cm
3min
-1for the
third house and so on.
By using at least 3 different methods, calculate the total volume of water
used by all the houses in 1 minute, if all the housing estate are using the
water at the same time.
22
Task 3
Assuming that the shape of the tank to be built is a cuboid with a base dimension
of site (p x p) m
2and a height h m as as shown in figure 1 and the volume of the
tank is 50 m
3, find the minimum surface area needed to built the given tank.
25
Task 4
If the number of houses in the housing estate increases in the future, what
is the maximum number of houses that can be built so that the supply of
water from the tank can fulfil the demand of the residents.

Conclusion
After doing research, answering questions, drawing
graph, some problem solving, I saw that the usage of
differentiation and arithmatic progression is important in
daily life. It is not just widely used in markets but also in
interpreting the condition of the surrounding like the air
or the water. Especially in conducting an air-pollution
survey. In conclusion, statistics is a daily life essecities.
Without it, surveys can’t be conducted, the stock market
can’t be interpret and many more. So, we should be
thankful of the people who contribute in the idea of
statistics
