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

Step-by-step explanation:

When you write

          -1

y = sin    x, the "-1" is not an exponent, but rather an indication of "inverse function."

          -1

y = sin    x      can also be written as     y = arcsin x.

No exponentiation here, and no division here.

f-1(x)= cube root of 19x squared/x
