    How to calculate cosec^2/sec^2/cot^2 on a calculator?

    As can be seen from the title, I have no idea how to input cosec/sec/cot and their squared counterpart into a calculator, specifically the fx-100 AU Casio calculator, or any Casio calculator in general. Please help!

    Also, please teach me how to calculate h in h^2=100^2/(cot^2(62°))*(cot^2(55)) while you're at it! 😅

    For cosec^2, enter 1/(sinx)^2
    For sec^2, enter 1/(cosx)^2
    For cot^2, enter 1/(tanx)^2

    Its just inverses. You dont have specific keys to type them in

    Well actually they're reciprocals... the inverse functions etc. are different.
