Step 2: Try a couple more -values to simulate the feeling of getting infinitely close to from the left.
Why avoid picking -values in constant increments like or even?
Avoid picking -values in constant increments like or even because those values don't really get us infinitely close—the y only get us kind of close. To get infinitely close, we want to keep reducing our increments, using -values like , so that we’re shrinking the space between where we are and where we’d like to be.
