Question about Casio FX-115ES Scientific Calculator
I am not sure what you mean, because your question already shows what you have to do.
To use the functions marked on the body of the calculator you use either the SHIFT key for the ALPHA key.
If a key has next to it (on the body of the calculator) two markings, the one on the left is accessed with SHIFT, and the one on the right with ALPHA. Colors of commands on calculator body are coordinated with the colors of the Shift key and the ALPHA key.
The question I am asking is whether you know what [SHIFT][COS] means. You probably do, but just in case you do not (no reflexion on your abilities)
[SHIFT] [COS] gives access to the arc cosine function, [SHIFT][SIN] the arc sine function, and [SHIFT][TAN] the arctangent.
