Answer 2

It looks like you're asking for the value of the expression:

Tg(arctg(2) - arccos(12/13))

I'm assuming by "Tg" you mean the tangent function (usually abbreviated as "tan"), "arctg" is the arctangent function (also known as "atan"), and "arccos" is the arccosine function (also known as "acos").

Let's break down the expression step by step:

1. Calculate the value of arctg(2): arctg(2) is the angle whose tangent is 2. arctg(2) is approximately 1.107 radians or 63.43 degrees.

2. Calculate the value of arccos(12/13): arccos(12/13) is the angle whose cosine is 12/13. arccos(12/13) is approximately 0.497 radians or 28.57 degrees.

3. Subtract the second result from the first result: arctg(2) - arccos(12/13) ≈ 1.107 - 0.497 ≈ 0.61 radians or 34.86 degrees.

4. Calculate the tangent of the final result: tan(0.61 radians) ≈ 0.684

So, the value of the expression tan(arctg(2) - arccos(12/13)) is approximately 0.684.
