Limits In Layman Terms

ByZulqai

Imagine you are walking towards a wall. Every step you take, you cover half the remaining distance:

  • First step: You go halfway.
  • Second step: You go half of what’s left.
  • Third step: Again, half of what’s left.

Even though you never actually touch the wall, you get closer and closer.

👉 The limit here is you reaching the wall—even if you technically never step exactly on it.

Here is another analogy to understand limits in layman terms:

You’re driving on a highway, and you see a speed limit sign: 70 km/h.

  • You start at 0 km/h.
  • You accelerate: 10, 30, 50, 65, 69, 69.9…
  • You get closer and closer to 70 km/h but never actually hit it exactly.

👉 The limit is 70 km/h, because that’s the speed you are approaching.

Why is This Important?

  • Limits help us define derivatives (which measure rates of change).
  • They explain continuous and smooth changes in functions.
  • Essential for calculus and real-world applications like physics and ML.
