What is a good calculator for trigonometry?

Answer 1

Any calculator sold as a "scientific calculator" has the basic trigonometric functions (sin, cos, tan) and the inverse trigonometric functions (arc-sin, arc-cos, arc-tan). That's about all you need.You can also use the calculator that comes on your computer - for example, in Windows, press Windows-R, and then type "calc". You may have to change the calculator mode, to "scientific calculator".

Yet another option is a spreadsheet, for example, Excel. Note that in Excel, angles are expressed in radians; if you want degrees, you also need the special functions to convert degrees to radians, or radians to degrees.

However, if you want to do your homework while you are NOT at your computer, you are better off buying a calculator.
