$\sin^2 (x)$ is the worst notation anyone has ever come up with. There was absolutely nothing wrong with $\sin (x)^2$ , and putting the exponential before the parameter only introduces more confusion when talking about inverse functions.

$\sin^{-1}(x)$ is the inverse function, not the reciprocal. It's only because of the above shitty notation that we have this confusion.

a lot of the times in written math you omit the parantheses around the argument of the function. not really trying to defend it but it's understandable why it exists

You can also be a pedantic prick and say something retarded like
> $\sin^{-1}(x)$ is the preimage of $x$ under the map $\sin$

It is true for exactly two values of x

$x = \pm 0.94403...$

>the inverse function, not the reciprocal
the reciprocal is the same things as the multiplicative inverse (or just inverse) you mouthbreather nigger

"pedantic" is a pejorative only among those who do not value education.

I don't value senseless obfuscation to make things the slightest bit more precise

Don't do math then if you can't handle being precise about what you are discussing and would rather discuss ill defined ideas
