I don't have the shift key on my Casio fx 92

How can I switch from cos to the angle?

Thank you

    Hello

    Use the cos-1 function. You get it by pressing the blue second key and then the cos key:

    Check:

    cos-1(0.5) = 60 °

    What is well conceived is expressed clearly,
    And the words to say it come easily.
