When `x lt 3`, find the values of `1//x`.

Explanation

To solve the problem of finding the values of \( \frac{1}{x} \) when \( x < 3 \), we can follow these steps:

### Step 1: Understand the function
The function we are dealing with is \( y = \frac{1}{x} \). This function is defined for all \( x \) except \( x = 0 \) (since division by zero is undefined).

### Step 2: Identify the domain
We are interested in the values of \( x \) that are less than 3. Thus, we can express the domain as:
\[ x \in (-\infty, 0) \cup (0, 3) \]
