for Njosh

You have been engaged to develop a graphical calculator. Specific requirements are as follows:

Create a graphical calculator with buttons that can add, subtract, multiply, divide, +/-, Sin, Cos, Tan, clear, and Modulus.

Write a method for each of these calculations that will accept the needed incoming numbers and return the calculated value.

• Please note the call to these methods will occur when = is pressed.
• You may only use 1 textbox to input numbers and display the results.

Please submit your assignment.

For assistance with your assignment, please use your text, Web resources, and all course materials.

Project CriteriaExceeds: 90%–100%Very good: 80%–89%Meets: 70%–79%Needs Improvement: Below 70%

Content (75%)

Response covers all topics indicated in the assignment and adds additional content.Response covers most topics indicated in the assignment.Response covers many of the topics indicated in the assignment.Response covers none to some of the topics indicated in the assignment.

Effective Communication(10%)

Demonstrates outstanding or exemplary application of written, visual, or oral skills. Demonstrates outstanding expression of topic, main idea, and purpose. Audience is addressed appropriately. Language clearly and effectively communicates ideas and content relevant to the assignment. Errors in grammar, spelling, and sentence structure are minimal. Organization is clear. Format is consistently appropriate to assignment. Presentation and delivery are confident and persuasive (where applicable). The writing was of collegiate level with no errors in spelling or grammar.Demonstrates very good written, visual, or oral skills. Demonstrates sound expression of topic, main idea, and purpose. Audience is usually addressed appropriately. Language does not interfere with the communication of ideas and content relevant to the assignment. Errors in grammar, spelling, and sentence structure are present, but do not distract from the message. Organization is apparent and mostly clear. Format is appropriate to assignment, but not entirely consistent. The writing was of collegiate level with two or less errors in spelling or grammar.Demonstrates acceptable written, visual, or oral skills. Demonstrates reasonable expression of topic, main idea, and purpose. Sometimes, audience is addressed appropriately. Language does not interfere with the communication of ideas and content relevant to the assignment. Errors in grammar, spelling, and sentence structure are present and may distract from the message. Organization is a bit unclear. Format is inconsistent. The writing was of collegiate level with several errors in spelling or grammar.Demonstrates inadequate or partially proficient application of written, visual, or oral skills. Demonstrates inadequate or partial expression of topic, main idea, and purpose. Audience is often not addressed appropriately. Language often impedes the communication of ideas and content relevant to the assignment. Errors in grammar, spelling, and sentence structure are frequent and often distract from meaning or presentation. Organization is inadequate, confusing, and distracting. Format is inadequate and obscures meaning. The writing was less than collegiate level with numerous errors in spelling or grammar.

Supporting Analysis(15%)

Analysis exceeds minimum requirements. Sources are used to support analysis, are appropriate, and are properly referenced.Basic analysis provided to support assertions. Sources are cited, appropriate, and properly referenced.Limited analysis provided to support assertions. Some sources are cited, appropriate, and properly referenced.No or inaccurate analysis, no sources are cited when needed, analysis and/or sources are not appropriate. When sources used, are not properly referenced.

Instructor's Comments:

Class:

1. note that for our IP-4 C# calculator program discussed during our chat session in addition to the labels to request two numbers, the text boxes to allow end user to enter the two numbers, and the various control boxes, you still need a label to display the calculation results.
2. Be sure to verify the following Libraries for your project, otherwise include them:

          using System;           using System.Collections.Generic;           using System.ComponentModel;           using System.Data;           using System.Drawing;           using System.Linq;           using System.Text;           using System.Windows.Forms;

1. You need to convert the numbers entered into the text boxes, i.e.

           Number1 = Convert.ToDouble(txtOutput.Text);

1. You need to convert calculation prior to displaying within the label (see point#1 above), i.e.

         txtOutput.Text = Math.Sin(Convert.ToDouble(txtOutput.Text)).ToString();

         txtOutput.Text = Math.Tan(Convert.ToDouble(txtOutput.Text)).ToString();

         txtOutput.Text = Math.Cos(Convert.ToDouble(txtOutput.Text)).ToString();
