asin in formula for arithmetic questions

Taha.M.106

It seems that asin is not supported. Does anyone know how to handle that? The answer for one of the questions I am trying to write is an "asin(x)"

Thanks

Finally figured it out. Here how it goes:

if we write: asin(x) = y

with some trig manipulation: tan(y) = sqr((x)^2)/( 1 – (x)^2)

and y=atan(sqr((x)^2)/( 1 – (x)^2))

I wish that the function was supported instead.
