To find the values of all six trigonometric functions for an angle β whose terminal side goes through the point \((13, -15)\), we need to follow these steps:

### Step 1: Find the Hypotenuse (Radius)
The hypotenuse (or radius, \( r \)) is calculated using the distance formula:
\[
r = \sqrt{x^2 + y^2}
\]
where \( x = 13 \) and \( y = -15 \).

\[
r = \sqrt{13^2 + (-15)^2} = \sqrt{169 + 225} = \sqrt{394} \approx 19.8
\]

### Step 2: Define the Trigonometric Functions
Using \( x = 13 \), \( y = -15 \), and \( r \approx 19.8 \):

1. **Sine** \(\sin(\beta) = \frac{y}{r}\):
   \[
   \sin(\beta) = \frac{-15}{19.8} \approx -0.8
   \]

2. **Cosine** \(\cos(\beta) = \frac{x}{r}\):
   \[
   \cos(\beta) = \frac{13}{19.8} \approx 0.7
   \]

3. **Tangent** \(\tan(\beta) = \frac{y}{x}\):
   \[
   \tan(\beta) = \frac{-15}{13} \approx -1.2
   \]

4. **Cosecant** \(\csc(\beta) = \frac{r}{y}\):
   \[
   \csc(\beta) = \frac{19.8}{-15} \approx -1.3
   \]

5. **Secant** \(\sec(\beta) = \frac{r}{x}\):
   \[
   \sec(\beta) = \frac{19.8}{13} \approx 1.5
   \]

6. **Cotangent** \(\cot(\beta) = \frac{x}{y}\):
   \[
   \cot(\beta) = \frac{13}{-15} \approx -0.9
   \]

### Summary of Correct Values
- **\(\sin(\beta) \approx -0.8\)**
- **\(\cos(\beta) \approx 0.7\)**
- **\(\tan(\beta) \approx -1.2\)**
- **\(\csc(\beta) \approx -1.3\)**
- **\(\sec(\beta) \approx 1.5\)**
- **\(\cot(\beta) \approx -0.9\)**

From the image, it appears that the errors are in the **secant** and **cotangent** values. The correct values should be:
- **sec(\(\beta\)) ≈ 1.5**
- **cot(\(\beta\)) ≈ -0.9**
