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?

In summary, $\tan^2 (x)$ is the same as $(\tan x)^2$, while $\tan (x)^2$ is not proper notation as it is unclear whether the argument or the function is being squared. Some may use it as a shorthand for $\tan^2 (x)$, but it is not universally accepted.

$\tan(x)^2$ 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.

Yes, they are both proper notations for the trig function tangent squared. The ^2 simply indicates that the function is being squared.

Yes, both notations are acceptable and will give the same result. However, it is important to be consistent with notation throughout your work.

The ^2 indicates that the function is being squared, meaning it is being multiplied by itself. This is to distinguish it from the function tangent, which is written as tan(x) without the exponent.

Yes, the parentheses do not change the meaning in this case. Both notations indicate that the function tangent is being squared.

No, this would not be proper notation for tangent squared. The ^2 should always come after the function, not inside the parentheses.
