Is tan^2 (x) the same as tan(x)^2?

Note: I could have used any trig function.

I know that tan^2 (x) means (tan x)^2.
What does tan (x)^2 mean? Is it proper notation?

I don't consider \(\displaystyle \tan(x)^2\) to be proper notation. It is unclear whether the argument or the function is being squared.

I concur.
