Instructions

Open the application

Running from command line:

• In the command line, navigate to folder: COMP_354_project_Team_M /Application/COMP_354_project_Team_M_jar
• Once you are in the folder, type in the command line: java -jar COMP_354_project_Team_M.jar

Running from IDE:

• Open package COMP_354_project_Team_M using your preferred IDE
• Run class UI.java located in src/eternity/math/UI.java

Use the software

From the Main Menu, type the option number you want and hit enter:

• 1 for Algebra calculator
• 2 for Finance calculator (Mean Absolute Deviation and Standard Deviation)
• 3 for Settings
• q to exit the program

Algebra Calculator:

Algebra Calculator allows you to calculate algebraic equations.

• From the Algebra Calculator Menu, type the equation you want to evaluate and hit enter
• Some examples of equations:

•   1+2.5+pi
  

•   sinh(1+2.5)
  

•   sin(pi/2)
  

•   2^(5+5) + e
  

•   arccos(0.5) + 2^6
  

•   log(2,8) + 3.4 + log(100)
  

  • log(2,8) for log base 2 of 8
  • log(100) for log base 10 of 100

Notes: Please make sure to put the variables inside brackets for these functions:

• sin(), cos(), arcsin(), arccos(), sinh(), log(), sqrt()

Finance Calculator:

Finance Calculator includes two statistical functions: Mean Absolute Deviation and Standard Deviation.

• From the Finance Calculator menu, type the option number you want and hit enter:
  • 1 for Mean Absolute Deviation
  • 2 for Standard Deviation
• To use the Mean Absolute Deviation or Standard Deviation calculators, enter the series of variables separated by a space, and hit enter
• Some examples:

• 1 2 3.4 5 44
  

• 100 200 300 10 12
  

• 1.1 2.22 3.333
  

Settings:

Settings option allows you to change the decimal places of ETERNITY or switch ETERNITY between Degree and Radian mode

• From the Settings menu, type the option number you want and hit enter:
  • 1 for Decimals
  • 2 for Degree/Radian
