How to Create an Issue

PLEASE FIND YOUR APPROPRIATE ISSUE AND USE THAT TEMPLATE

A Few Tips

• To link to a page, use square brackets followed by parentheses. In the square brackets, include the the text of the hyperlink to show, and place the URL in the parenthesis. "[Math.java] (https://github.com/Kyle-P/Mathematics)." To make this an actual hyperlink, remove the space between the closing square bracket and the left parentheses.

Fixing a Bug

Please fix [error occuring] in the [filename].java program.

• Description of the issue
• How it can be fixed

Creating a New Program

Create a program to find [what is calculated]. The program should go under the [Subject] folder. Title the program [Math Concept].java.

Refer to [similar program] to find out how to prompt users for data and use it accordingly.

If you are a first time contributor, welcome! Please read through the basic guidlines
as well as the contribution guidelines before getting started.

Real Example:

"Create a program to find the slope of a line given two points on the line. The program should go under the Algebra folder. Title the program SlopeOfALine.java.

Refer to the quadratic formula code to find out how to prompt users for data and use it accordingly."

If you are a first time contributor, welcome! Please read through the basic guidlines
as well as the contribution guidelines before getting started.

Background: Each explanation file should include a "Using Our Program" section as detailed in CONTRIBUTING.md.

Please add a "Using Our Program" section in the Area Program. Good template to follow: https://github.com/Kyle-P/Mathematics/blob/master/Algebra/SlopeOfALineExplanation.md

Create a program to find the slope of a line given two points on the line. The program should go under the Algebra folder. Title the program SlopeOfALine.java.

Refer to the quadratic formula code to find out how to prompt users for data and use it accordingly.

The prime factors program currently only displays which factors of a given number are prime.

Develop a feature to give the actual prime factorization of the user-inputted number. For example, instead of calculating "1 and 3" for the prime factors of 9, display 3*3.

Create a FactorsExplanation.md file for the factors of a number program. Check other explanation files for an example of how to do this. Thank you!

Math Level: Algebra

The TravisCI build state in the README file under the "Continuous Integration" section shows "build [status]." Please also find a way to automatically add in the additional information shown at the bottom of this page.

Thank you!

Please rename the Gui folder to GUI. This is just a preference. This can only be done with Git.

Thanks!

The sineh, cosh, tanh, arcsine, arccosine, and arctan functions don't seem to output the correct answers in the trigonometry calculator.

For sineh, cosh, and tanh, the programs seems to be returning values for sin, cos, and tan rather than the sineh, cosh, and tanh function calculations.

For the inverse functions (arcsine, arccosine, arctangent), remember that the input is not an angle, but rather a number that is the result of calculating sine, cosine, or tangent on an angle. These functions aren't returning the correct output in the program.

Thanks so much for contributing to our repo! It's very appreciated.

TravisCI is now set up. Previous errors were coming up because no programming language was specified. In the .travis.yml file, Java is now specified. Just need the script.

For the script, would you be able to make sure:

1. The code is commented.
2. The code runs without errors.

Thank you!

Please add an explanation to users for how the zeroes were computed based on the quadratic formula program.

Remember that each program must explain to users how answers are generated rather than just providing an answer.

For the script, would you be able to make sure the code just runs without errors for now?

Thank you!

Issue Templates

Please add a SlopeOfALineExplanation.md file discussing the concept of the slope of a line as well as the equation, how to use it, etc. Be sure to include undefined slopes, 0 slopes, etc in your explanations.

An example of a well-done explanation file can be found at https://github.com/Kyle-P/Mathematics/blob/master/Geometry/HeronExplanation.md.

Thanks!

The IVT Calculator does not properly check for continuity. Even if the user enters "no" when prompted whether or not the function is continuous, the program moves on.

Prevent the above from occurring. When the function isn't continuous, the program should stop running and display the appropriate exit message.

Please add an explanation to users for how the Intermediate Value Theorem is applied in order to compute the correct answer in the IVT Calculator.

Remember that each program must explain to users how answers are generated rather than just providing an answer.

Please go through the current Java programs and ensure that each program ends with a new line. There is at least one program without a new line at the end.

This is just a matter of preference for Java but is a necessary step in other programming languages.

Background: Each explanation file should include a "Using Our Program" section as detailed in CONTRIBUTING.md.

Please add a "Using Our Program" section in the Heron Explanation README. Good template to follow: https://github.com/Kyle-P/Mathematics/blob/master/Algebra/SlopeOfALineExplanation.md

@Kyle-Pu, I spent the time to start setting up a proper build architecture on a separate branch, but rights aren't available to create a branch. Is this the desired behavior?

Welcome to our Mathematics repository! Please read over the README file and the contributing file to get a feel for how this repo operates.

Every idea for a new program will be hosted at our IDEAS page.

This issue was opened to create visibility for where available coding opportunities are. Ideas will be added to this list as they are added to our IDEAS.md page mentioned above. This list will be maintained and updated as the IDEAS page is updated.

Feel free to get started on a program and thanks for your contributions!

If the user enters an incorrect data type in the slope of a line calculation program, the program displays a warning message and prompts users to restart.

Please create a function to allow users to restart the program with a key such as 'R,' or any other easy-to-restart way.

Add new ideas for calculator program in our ideas list! Please be sure to format entries correctly and that each idea goes under the appropriate subject.

This is an ongoing effort, so this issue will always stay open.

There have been a few typos found in the documentation docs such as the README.md, contribution guidelines, etc.

Please read through each file and check for any typos or anything that doesn't seem clear. Comment below what could be improved, or create a pull request to fix the issue yourself!

If no issues are found, feel free to comment that nothing was found and this issue will be closed.

Hello everyone,

I tried to make a code analysis for this project. For my analysis I used the enviroment of InteliJ using the CodeMr plug in.
I attatched you my results in the pdf file.

codeAnalysis.pdf

The quadratic formula calculator returns "NaN" when no value for a zero is found.

Instead print out: "No zero found."

Please move the .class files to their respective folders in the Algebra folder. Please do the same for the trigonometry folder. Thanks!

Please add an explanation to users for how the the area of the inputted triangle computed in
Heron's Area Calculator.

Remember that each program must explain to users how answers are generated rather than just providing an answer.

Fix Rounding Error in the Volume.java program.

• volume divides int by an int which causes rounding error
• Can be fixed by changing one of the numbers to float

If the user enters an incorrect data type in the slope of a line calculation program, the program displays a warning message and restarts the program using the following code:

//Automatically restarts the program
 String[] a = new String[1];
 main(a);

Please create a better way to restart the program.

Please edit the formatting of the HeronExplanation Document so the appropriate mathematical symbols are displayed to users rather than the math functions such as "sqrt()."
