There should be no problem with the whole method. . However, (1) when m= 1, 2, 3, there is something wrong with the statement that the conjecture is obviously true. . M= 1 M=2 should be singled out. . 1) When m=3.4, the conjecture obviously holds, because you can't fit your conjecture at 1.2. . M 1m2 is calculated separately. . Prove the conjecture from 3. . . It won't be a problem. . But the method is a bit troublesome. It is more convenient to directly follow the equal proportion and formula. . . .
