PLZ help

If you need to do cosec 20 on your casio calculator how would you do it and
how would you do it on a 100 AU casio calculator

couldnt you just use the reciprocal ie 1/sin20?

secθ = 1/cosθ
cosecθ = 1/sinθ
cotθ = 1/tanθ

For cotθ, you can also use cotθ = tan(90-θ), so for example, cot50^o = tan(90-50) = tan40^o
