Unit 11: Maths for Computing (L4) Session: September 2021 Coursework

You are strongly advised to read “Preparation guidelines of the Coursework Document” before answering your assignment.

ASSIGNMENT

Aim & Objective

This assignment is designed so that it enables the student to demonstrate their understanding of the mathematical concepts covered in the module through answering various practical problems; divided into four parts. The coursework should be submitted as one document in a report format in final submission.

Part 1 Unit 11: Maths for Computing

Number theory

The GCD (greatest common divisor), LCM (lowest common multiple) and prime numbers is used for a variety of applications in number theory, particularly in modular arithmetic and thus encryption algorithms such as RSA. It is also used for simpler applications, such as simplifying fractions. This makes the GCD, LCM and prime numbers a rather fundamental concept to number theory, and as such several algorithms have been discovered to efficiently compute it. Primes are the set of all numbers that can only be equally divided by 1 and themselves, with no other even division possible. Numbers like 2, 3, 5, 7, and 11 are all prime numbers.

Demonstrate the concepts of greatest common divisor and least common multiple of a given pair of numbers with an example. To support the evidence of your understanding on LCM and GCD, you should present with pseudocode and a computer program in python to compute LCM and GCD based on user’s input. It is desirable, to support your findings by identifying multiplicative inverses in modular arithmetic with an example. Produce a detailed written explanation of the importance and application of prime numbers in RSA encryption (Rivest–Shamir–Adleman). To support the evidence of your understanding on the use of prime numbers, you are required to develop a computer program in C/ C++ or python to demonstrate the asymmetric cryptography algorithm.

Sequences and Series

Arithmetic progressions are used in simulation engineering and in the reproductive cycle of bacteria. Some uses of AP’s in daily life include uniform increase in the speed at regular intervals, completing patterns of objects, calculating simple interest, speed of an aircraft, increase or decrease in the costs of goods, sales and production and so on. Geometric progressions (GP’s) are used in compound interest and the range of speeds on a drilling machine. In fact, GPs are used throughout mathematics, and they have many important applications in physics, engineering, biology, economics, computer science, queuing theory and finance.

To support the evidence of your understanding on AP and GP, solve the following 4 problems.

  1. The cost of painting walls of a room is £100 for first m2 and rises by £50 for each m2. Find the charge to paint all the walls of a room if the total area is 150 m2.
  2. An Arithmetic Progression has 23 terms, the sum of the middle three terms of this arithmetic progression is 720, and the sum of the last three terms of this Arithmetic Progression is 1320. What is the 18th term of this Arithmetic Progression?
  3. Find the sum of the first 20 terms of the GP with first term 3 and common ratio 1.5.
  4. The sum of the first 3 terms of a geometric series is 37/8. The sum of the first six terms is 3367/512. Find the first term and common ratio.
  5. How many terms in the GP 4, 3.6, 3.24, . . . are needed so that the sum exceeds 35?

Part 2 Unit 11: Maths for Computing

Probability theory and probability distributions

The probability of something to happen is the likelihood or a chance of it happening. Values of probability lie between 0 and 1, where 0 represents an absolute impossibility and 1 represent an absolute certainty. The probability of an event happening usually lies somewhere between these two extreme values and it is expressed either as a proper a decimal fraction.

2.1 To support the evidence of your understanding on probability theory and probability distributions, solve the following problems.

  1. What is the probability of getting a sum of 9 when two dice are thrown?
  2. A coin is thrown 3 times. what is the probability that at least one head is obtained?
  3. From a pack of cards, two cards are drawn at random. Find the probability that each card is numbered and from different suite.
  4. A bag contains 8 white, 4 red and 7 blue balls. Three balls are drawn at random from the bag. What is the probability that

i) all of them are blue.

ii) two is white and the third is red.

  1. Find the probability distribution of boys and girls in families with 5 children, assuming equal probabilities for boys and girls. Draw the graph of your probability distribution.
  2. The time taken to assemble a car in a certain plant is a random variable having a normal distribution of 20 hours and a standard deviation of 2 hours. What is the probability that a car can be assembled at this plant in a period of time?

a)  less than 19.5 hours?

b)  between 20 and 22 hours?

  1. The annual salaries of employees in a large company are approximately normally distributed with a mean of £40,000 and a standard deviation of £20,000.

a) What percent of people earn less than £30,000?

b) What percent of people earn between £35,000 and £45,000?

c) What percent of people earn more than £50,000?

It is also desirable to support your findings by producing a brief evaluation report on the use of probability theory in hashing and load balancing.

Part 3 Unit 11: Maths for Computing

Forces, velocities, and various other quantities are vectors functions find their applications in engineering, physics, fluid flow, electrostatics, computational maths and so on. The engineer must understand these fields as the basis of the design and construction of systems, such as airplanes, laser generators, thermodynamically system, or robots. In three dimensions, geometrical ideas become influential, enriching the theory. Thus, many geometrical quantities can be given by vectors.

To support the evidence of your understanding on geometry and vectors, solve the following problems

3.1 Find the equation of the line passing through (5, 7) and parallel to the line 5x – 7y = 4.

3.2 What is an equation of the line  that  goes  through  (−1,  −3)  and  is  perpendicular  to  the line 2x+7y+5=0?

3.3 Discover the estimation of h for which the lines 6x+5y+8=0 and 5x-hy+8= 0 are

(i) perpendicular to each other

(ii) parallel to each other

3.4 Explain the concepts of vector graphics in a computer system.

To present your further understanding on coordinate systems, you are required to evaluate the coordinate system used in programming a simple output device (Use a computer screen as an example of the output device in your evaluation). You should also present your findings on how to construct the scaling of simple shapes; like Triangle, circle, or a straight line in vector coordinates and visually by programming and simulating in Python or any other programming language. Unit 11: Maths for Computing

Part 4:

Calculus (Differential and integral calculus) is deeply integrated in every branch of the physical sciences, such as physics and biology. It is found in computer science, statistics, and engineering, in economics, business, and medicine. Among the many applications in computer science, numerical calculations, systems modelling and problems involving the performance of algorithm can be cited as examples. In this task you will demonstrate your understanding of differential and integral calculus.

To support the evidence of your understanding on Calculus, solve the following problems

4.1  Suppose that x = f(t) = ¼*t2 - t + 2 denotes the position of a bus at time t.

(a)  Find the velocity as a function of time; plot its graph.

(b)  Find and plot the speed as a function of time.

(c) Find the acceleration.

4.2  Sand is pouring out of a tube at 5 cubic cm per second. It forms a pile which has the shape of a cone. The height of the cone is equal to the radius of the circle at its base. How fast is the sandpile rising when it is 10 cm high?

4.3  Find the maximum and minimum value of the function

x3 - 3x2 - 9x + 12

4.4  Find the dimensions of a rectangle with perimeter 1000 metres so that the area of the rectangle is a maximum.

4.5  If the region bounded above by the graph of the function f(x)= x2 - 6x + 9 and below by the graph of the function g(x)=x+3 over the interval [x, y] is represented as R, find the area of Region R.

4.6  Find the area between the two curves y = x2 and y = 2x – x2
