    Sir I have a question why didn't you differentiate the 62.5 . Why does it not bcme 0 since it is just a n.o

      The 62.5 is multiplied so it does not become zero. For example, if you differentiate 3x you get 3. The 3 does not become zero. On the other hand if you differentiate 3 + x you get 1. The 3 becomes zero and you get 1 when you defferentiate the x.
