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 a user interface for the solution of quadratic equations. 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.
The following analyses should be completed at the commencement of this project:
User Analysis – who will be using the system
Display Content Analysis – what needs to be displayed
Work Environment Analysis – what is the platform/environment/architecture
Interface Design Steps – what are the interface objects and actions refer to Pressman’s chapters on Interface Design as well as Hix and Hartson.After these analyses have been completed, you should decide on the software tools which you will use. Justify these in your report.
For example, for the graphics you might choose from: Microsoft Word (using the SmartArt, Shapes, Pictures features), Microsoft Paint, Microsoft Powerpoint, GIMP (www.gimp.org), Adobe Acrobat, Enterprise Architect (EA), Inkscape (www.inkscape.org), Photoshop, Paint.net or possibly from Web Tools such as Dreamweaver. Justify your choices in your report. You will need to model the application; you may choose any model discussed in lectures such as
DFD, FSM, SASD, ERD, CSPEC and justify your choice of model or combination of models.Demonstrate the usefulness of your modelling.You will need to provide a State Chart Diagram (State Transition Diagram) of your application as
As there is no programming required in this assignment, you are encouraged - but not obliged to use Wolfram|Alpha (https://www.wolframalpha.com/) to solve your quadratic equations. Wolfram|Alpha is a free-form input computational knowledge engine using natural language. For example you could type “2 + 3” or “what is 2 + 3” or “what is the sum of 2 + 3”.Your GUI should appear to be solving the equations and you may use any relevant output generated from Wolfram|Alpha in your GUI.
