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

1. ## 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! 😅  Reply With Quote

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

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

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