👉 Infinitesimals, also known as limits of infinitesimal quantities, are a fundamental concept in mathematics and physics. They represent small changes in quantities that approach but never reach zero. Infinite means "unlimited," and infinitesimals capture these concepts by allowing for infinitely small changes without ever reaching infinity (which is the concept of infinity itself). The idea behind infinitesimals is to capture quantitatively how close something can be to a given value, while still being infinitely precise. This approach
