Answer 2

It seems like you've provided a mathematical expression involving trigonometric functions. Let's break down the expression step by step:

Given expression:

Tg^2(a) / (1 + tg^2(a)) * (1 + ctg^2(a)) / (ctg^2(a) - tg^2(a))

Here, "tg" represents the tangent function and "ctg" represents the cotangent function.

Step 1: Simplify each part of the expression.

• Tg^2(a) / (1 + tg^2(a)) simplifies to 1 - This is a trigonometric identity: 1 - tg^2(a) = 1 / (1 + tg^2(a)).

• (1 + ctg^2(a)) / (ctg^2(a) - tg^2(a)) simplifies to -1 - This is also a trigonometric identity: ctg^2(a) - tg^2(a) = -1.

Step 2: Substitute the simplified values back into the expression.

1 * (-1) = -1

So, the simplified expression is -1.
