Software Engineering Methodologies
Assignment 1 Individual Roots of Polynomials-Quadratic
Overview
This assignment requires you to analyse a problem and to design and implement a solution, which the user interacts with, via a GUI. The tasks required of your program will require you to demonstrate your understanding of the concepts covered in Weeks 1-3 of the course setting the foundations and a brief introduction to the course.
Timelines and Expectations
Percentage Value of Task: 20%
Due: Sun, April 16, 2017 - 16:00 (Week 7) Minimum time expectation: 10 hours
Learning Outcomes Assessed
S1. Critically analyse and use complex decision making to research and determine the appropriate Software Engineering tools and methodologies to utilize in a given situation.
S2. Apply professional communication skills to support and manage the engineering of a large software system.
S3. Review, critically analyse and develop artefacts to define processes for quality assurance, risk management and communication in large software development projects.
S4. Implement quality assurance activities in order to verify user requirements and validate design decisions.
A1. Analysis of a large system development problem to decide upon the best methodological approach.
Assessment Details
The application of quadratic equations is boundless; examples that spring to mind are parabolic paths of projectile motion, velocity in a gravitational field, optimization of profit/loss, and the golden ratio being just a few.
In this task you are required to design and implement a user interface for the solution of quadratic equations. The user is presented with a GUI in which they can either enter the parameters or specify a file from which parameters may be read. The quadratic solutions should be clearly

shown as well as proof that they do solve the quadratic equation. Feedback should be given to the user if invalid data is entered.
Your GUI should address the following requirements.
Requirements:
1. Application must provide the user with all roots of the general quadratic equation
y x( ) =ax bx c2 + +
For example, it must be able to solve equations of the type: y x( ) = +x2 1, y x( ) = - +x2 4x 3, y x( ) = 3.5x2 +5.5x+11.5 and any variations thereof.
2. Application must be developed in Java using Swing.
3. The equation must be displayed to the user in a suitable form
4. The solutions must be presented in graphical and numerical form.
5. The solutions must be shown to be correct.
6. The interface must be designed according to best practice and aesthetics.
7. The user is presented with a graphic user interface (GUI) through which they use the system.
8. The user must be made aware of any invalid data entered.
9. A test suite must be developed which can be read in as a file of suitable format.
10. The user may also submit their data in file form.
The following analyses should be completed at the commencement of this project:
• User Analysis
• Display Content Analysis
• Work Environment Analysis
• Interface Design Steps

Feedback
Assessment marks will be made available in fdlMarks, feedback to individual students will be provided via Moodle or as direct feedback during your tutorial class Plagiarism:
Plagiarism is the presentation of the expressed thought or work of another person as though it is one's own without properly acknowledging that person. You must not allow other students to copy your work and must take care to safeguard against this happening. More information about the plagiarism policy and procedure for the university can be found at:
http://federation.edu.au/students/learning-and-study/online-help-with/plagiarism
Your support material must be compiled from reliable sources such as the academic resources in
Federation University library which might include, but not limited to: the main library collection, library databases and the BONUS+ collection as well as any reputable online resources (you should confirm this with your tutor).
Federation University General Guide to Referencing:
The University has published a style guide to help students correctly reference and cite information they use in assignments. A copy of the University’s citation guides can be found on the university’s web site. It is imperative that students cite all sources of information. The General Guide to Referencing can be purchased from the University bookshop or accessed online at:
