The CASIO fx-7 is a scientific calculator with all the basic scientific operations:
roots and powers, trigonometric functions and logarithms. It also does percentages and
has memory.
The "MODE"-key is for setting the angular mode. The current angular mode is shown using one of the symbols D, R or G at the far right of the display. It has auto power-off. Memory is not retained when the calculator is in the auto power-off state. To switch it back on press the "AC"-key. This calculator (as do many other CASIO scientific calculators) uses one and the same key for both the constant π as well as exponents. This works as follows. When you first enter digits, the "EXP"-key will enable you to enter the exponent, otherwise it will enter the constant π. |
