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.
A syntax error in a calculator while finding the critical angle using Snell's Law could be due to inputting incorrect mathematical expressions or not following the correct syntax for trigonometric functions. Review the input values, make sure the calculator is in the correct mode (degrees or radians), and ensure that the formula is entered correctly with the appropriate parentheses and trigonometric functions.
press the reset button on the back of the calculator that worked for me
press shift and then press mode, keep pressing if you didn't find the perticular mode
On many calculators, the MODE key/button is to set the calculator into degrees or radian angle measurment, that is, when you enter a value, it and all further values you enter will then either be understood by the calculator as a degrees or radian value for an angle.
Mode is a mathematical term. It stands for the value that appears most often in a set of numerical data.
They are all forms of average.
number that occurs the most amount of times.
It depends on what type of calculatorIf you press "Mode" on your calculator, you can change from Sci, Eng, and something else.
It depends on your calculator. You may find that you need to go to set up and then display mode.
mode means an average found by determining the most frequent value in a group of values
