1. The problem presents several equations involving logarithms and variables. 2. Let's analyze the first equation: $\text{ص} = \log \frac{1}{س}$. 3. Using the logarithm rule $\log \frac{a}{b} = \log a - \log b$, we rewrite it as: $$\text{ص} = \log 1 - \log س$$ 4. Since $\log 1 = 0$, this simplifies to: $$\text{ص} = -\log س$$ 5. This means the function is the negative logarithm of $س$. 6. The other equations are not solved here as per instructions to solve only the first problem. 7. The final simplified form of the first equation is: $$\text{ص} = -\log س$$
