This time, I will explain its derivation. We have been sending you various videos as part of our official proofs series, and by this point, I think you'll be starting to get the hang of proofs. In the end, all you have to do is: First, write down the differentiation formula according to the definition Put the formula you know in a form that you can use That's about it. Once you understand that, proving the formula isn't that difficult!
