ELI5: I have a hard time comprehending the concept of limits in calculus.

r/

What are limits about? I got an explanation “it’s like reading a book where you figure out how it’ll end, even though the last page is missing.” Huh?

    If you’re talking about a limit at infinity, it’s more like having a book with an infinite number of pages and figuring out what direction the book is headed as it goes on even though you can never get to the end of the book.

    But limits aren’t always limits as the function approaches infinity, you can find limits at any value. In that case it’s like having a book where you figure out what’s going to be on a page you don’t look at based on everything that’s happened before and after it.

    A limit is just what happens at the end of making something bigger or smaler.

    If you divide 10 by another number and make that number bigger and bigger what happens to the result?
    10/1 =10

    10/2 = 5

    10/10 = 1

    10/20 = 1/2

    10/100 = 0.1

    10/100 = 0.01

    So whats the limit? What value is this going towards? Yes uts getting smaler and smaler, so the limit of this is 0. It will never actualy reach zero, it just gets closer and closer to zero.
