## Answer

The problem statement gives us two trigonometric equations:

- $$ \tan(a-b) = 1 $$
- $$ \sec(a+b) = \frac{2}{\sqrt{3}} $$

We are asked to find the values for $a$ and $b$ given these conditions.

### Step-by-Step Analysis

**Equation 1 Analysis:**
The equation $\tan(a-b) = 1$ usually implies that $a-b$ could be equal to an angle where the tangent value is 1. The general solutions for this scenario are:
$$
a - b = \frac{\pi}{4} + n\pi
$$
where $n$ is any integer.

**Equation 2 Analysis:**
For the equation $\sec(a+b) = \frac{2}{\sqrt{3}}$, knowing values where $\cos$ is $\frac{\sqrt{3}}{2}$ is useful because $\sec$ is the reciprocal of $\cos$. This usually happens at:
$$
a + b = \pm\frac{\pi}{6} + 2n\pi
$$
Here again, $n$ is any integer.

### Solving for $a$ and $b$

Given the periodicity of trigonometric functions and the nature of these specific values, the most straightforward choice for $**n**$ would be $0$ to simplify calculations.

Thus, we have: $$ a - b = \frac{\pi}{4} $$ and $$ a + b = \frac{\pi}{6} $$

Adding these two equations, we get: $$ 2a = \frac{\pi}{4} + \frac{\pi}{6} = \frac{3\pi + 2\pi}{12} = \frac{5\pi}{12} $$ $$ a = \frac{5\pi}{24} $$

Subtracting the $a - b$ equation from the $a + b$ equation: $$ 2b = \frac{\pi}{6} - \frac{\pi}{4} = \frac{2\pi - 3\pi}{12} = -\frac{\pi}{12} $$ $$ b = -\frac{\pi}{24} $$

Hence, the values of $a$ and $b$ that satisfy both conditions are: $$ a = \frac{5\pi}{24},, b = -\frac{\pi}{24} $$

These values can of course vary by adding integer multiples of $\pi$ or $2\pi$, depending on the periodicity of the trigonometric functions involved.
