Prove the relations (1.2.3.11) with t defined at (1.2.3.10) !
(1.2.3.4) |
(1.2.3.10) |
(1.2.3.11) |
In order to prove the equations (1.2.3.11), we write:
The righthand side of the first equation from (1.2.3.11) can be rewritten according to the part 1:
But the righthand side of part 2 can be rewritten according to (1.2.3.4) as:
which completes the proof of the first equation from (1.2.3.11).
The righthand side of the second equation from (1.2.3.11) can be rewritten according to part 1:
But the righthand side of part 4 can be rewritten according to (1.2.3.4) as:
which completes the proof of the second equation from (1.2.3.11).
Correct and full proof of the first equation from (1.2.3.11) gives a 6 point credit to the user.
Correct and full proof of the second equation from (1.2.3.11) credits the user with 4 points. But if the proof of the first equation is scored zero, then the proof of the second equation is worth 6 points.Otherwise:
Part 1 is worth 2 points. Parts 2 and 4 are worth 3 points each. Parts 3 and 5 are worth 1 point each.
