Hey guys.

Can anyone explain to me why we use derivates, what does it give us ? I dont want to hear definition words. Explain to me like you would explain to a child. Simply and straightforward. No fancy words.

What does the definition of the derivative tell us? Why must we derive a funtion in such way to get the derivative? I understand that "that is what the formula saids". But im not here to only go by the formula. I want to understand. Everything has its reason and im looking for the explanation. Just explain it as simply as possibly.

Thank you
