Answer 2

Solution:

To solve the equation cos(2a) + tg(2a) + sin(2a), we need to use trigonometric identities and simplify the expression.

Let's break down the equation step by step:

1. Start with the identity tg(2a) = 2tg(a) / (1 - tg^2(a)). 2. Substitute this identity into the equation: cos(2a) + 2tg(a) / (1 - tg^2(a)) + sin(2a).

Now, let's simplify further:

3. Use the identity cos(2a) = 1 - 2sin^2(a). 4. Substitute this identity into the equation: 1 - 2sin^2(a) + 2tg(a) / (1 - tg^2(a)) + sin(2a).

We can simplify the equation even more:

5. Use the identity sin(2a) = 2sin(a)cos(a). 6. Substitute this identity into the equation: 1 - 2sin^2(a) + 2tg(a) / (1 - tg^2(a)) + 2sin(a)cos(a).

Now, we have a simplified equation. To solve it, we need additional information about the values of sin(a), cos(a), and tg(a). Unfortunately, the given equation does not provide this information.

If you have specific values for sin(a), cos(a), and tg(a), please provide them, and I will be happy to help you solve the equation.
