@Efi sin²(x) is usually the same as sin(x)² (and (sin(x))²).
When dealing with function/operators algebra, though, it's pretty common to have f²(x) mean f(f(x)), though.
(And yes, fuck this.)

@kellerfuchs @Efi
though fⁿ(x) frequently means the nth derivative of f

@kellerfuchs @Efi that's more clear. maybe i was taught a bad idiom
