In the same way it was traditionally agreed that exponentiation of a trig function can be written sin^n θ or as (sin θ)^n, because mathematicians are basically lazy and don't like to write anything extra


in sin^3, ^3 is not not an argument, it is itself a function w/ sin something as it's argument,

the rewrite is just a clearer way to represent the same thing

Thank you Bill.
