I imagine you want to achieve element-wise division. You can use the vectorize function.

Wondering if it's truly unsolvable in Smath since I cant have scalars there bc I have to vectorize the functions

The external function "asin" should be evaluated element-wise.

Don't confuse subscripts (obtained, for example, with a.1) with array or matrix indices (obtained, for example, with a[1).
