Question

Does sine inverse have an exponent? If not, why is there a negative one there? If so, why can't you just divide?

Answer 1

see below

Explanation:

the actual way of writing sin inverse is arcsine, not sin⁻¹

since the output of sin is from -1 to 1, the domain of arsince is from -1 to 1. This is different than 1/sin(x), whose domain is all real numbers. we now write sin⁻¹ to fit it on the tiny buttons on our calculators
