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

$\tan(x)^2$ is an acceptable form of syntax for $\tan^2{x}$ used in many calculators.

So long as the parenthesis are included in \(\displaystyle tan(x)^2\) I have no problem with the expression.
