Solve mathematical problems, even using text files, with Advanced Trigonometry Calculator
Advanced Trigonometry Calculator is a free, portable (no need to install it) and powerful program that lets you confront advanced mathematical problems.
The program features a panel where you write all necessary commands. Detailed documentation is also provided to let you gain some familiarity with the available commands.
A nice feature of Advanced Trigonometry Calculator is scripting, saving calculations to repeat them. You can also use your own functions in the expressions. Besides mathematical functions and expressions the program lets you use a calendar, a stopwatch, and more tools you may need in your work.
Advanced Trigonometry Calculator is free and powerful, but you need to feel able to work with command prompts instead of using the buttons of a pure GUI supported program.
