Hello, i can’t understand how these equations come from (with red rectanle)
Thanks
Hmm, i think i found it.
eq (1)
eq (2) - eq (1)
eq (3) - eq (1)
Yes.
This was also explained in the words that Prof Serrano was saying at the time that slide appeared in the lectures. If it didn’t make sense the first time through, it might be worth watching the lecture again. He also worked and explained similar examples with two variables in the previous two lectures.
Yes, you have right!
