      In this case you can divide the first equation by 2 to get x congruent to 3 mod 7 (you might like to prove that it is ok to do this). Do the same for the other equations and then use my video.

    • @RandellHeyman
      @RandellHeyman Před 9 měsíci

      Sorry you couldn't understand. There are of course other videos that might be better for you. Otherwise.... You are probably getting stuck around the 2 min mark. On the right hand side I show my workings to express 1 as the difference between multiples of 3000 and 197. From the last line on the left I have 6=1(5)+1. This means that 1=6-1(5). So I write that on the right. Now I want to get rid of that multiple of 5. To do that I look at the second last line on the left. This is 11=1(6)+5. This means that 5=11-1(6). So I can replace 5 in the first line on the right with 11-1(6). So then I get 1=6-1(11-1(6)). This means 1=2(6)-1(11), which is 2nd line on the right. Next I want to replace 2(6). To do this I use the 3rd last line on the left. This continues until I get to the last line on the right side.

    FERMAT n'a jamais utilisé tous ces calculs inconnus de son temps ! La solution est bien plus facile. Trouvez d'abord l'équation générale UNIVERSELLE cachée de FERMAT, valable quelle que soit la valeur de Zpuissance(N) et ENSUITE, vous en déduisez que Zpuissance(N) =Xpuissance(N) + Ypuissance(N) n'a pas de solution ! (conjecture de FERMAT).J'ajoute que c'est le plus beau CANULAR mathématique de tous les temps et c'est un mystère de voir autant de mathématiciens tomber dans le piège en formulant des théories inconnues de FERMAT .Il y en a même qui pensent que FERMAT n'a jamais eu la démonstration ! La démonstration est si courte et si facile que vous ne trouverez pas, cherchant une solution compliquée. Ce n'est pourtant pas difficile à comprendre ! Pour ceux que ça intéresse , afin de ne pas me répéter encore une fois, aller sur d'autres sites de FERMAT pour avoir plus d'explications de ma part..

  • @faridabdi3590

    The explanation for question one does not make sense to someone who knows nothing about this subject, the syntax and operations performed are inexplicable: Because Randell says 5 mod 3 = 2 mod 3 Without any explanation of why that is or how such a stupid looking syntax came about. Therefore not worth even trying to look at the other questions he aims to explain

      I think what I have in the video is correct; a_0 is meant to be divided by two. Go to 4'35" where I say for a_0 you just integrate both sides with respect to x between -pi and pi and then solve for a_0.
