Answer 2

It seems like you've entered "TT12dx4.5" and then asked about the mathematical expression "cos3 x." However, your input is not very clear. If "TT12dx4.5" is a variable or term, I'm not familiar with it as of my last knowledge update in September 2021.

Regarding "cos3 x," it's likely that you're referring to the trigonometric function cosine raised to the power of 3, which is written as $\cos^3(x)$. This can be expressed as the cube of the cosine of angle $x$.

If you have a specific question or context you'd like to discuss about "TT12dx4.5" or $\cos^3(x)$, please provide more details so that I can assist you accurately.
