Desmos and GeoGebra can both do this (though GeoGebra has little gaps in this particular example, and you'll need arcsin rather than asin for both tools). If you want programming-oriented, Sympy can do an okay job (asin), as can Numpy (arcsin), but the latter involves more mucking about, evaluating on a grid.
