minus-squareBeartotem@sh.itjust.workslinkfedilinkarrow-up1·2 months agoI’m just being a pendant here, but the derivative of x²+C is 2x. You put the constant at the wrong place. Also, i’m glad you found a textbook well suited for you. I have to wonder what you mean by ‘why’, do you mean a proof?
minus-squareCanadaPlus@lemmy.sdf.orglinkfedilinkarrow-up2·edit-22 months agoI’m guessing the derivation from first principles. I too learned the rules years before I was shown it, and it was just so cool to see where they came from.
minus-squaregramie@lemmy.calinkfedilinkarrow-up2·2 months agoThat’s exactly right. The proof is quite simple and there’s no reason it shouldn’t be taught instead of just getting students to accept magic rules.
