Kunagi oli miski teema lambamäägekaugustest.

Eeh, kunagi põhikoolis kui matemaatika tunnis ülesandeid lahendada ei viitsinud mõtlesin välja ilgelt laheda mootori. Koju jõudes tekkis kahtlus, et peaks järgi uurima ega sellist juba olemas ei ole. Oma pettumuseks olin tavalise reaktiivmootori põhimõttelise skeemi paberile kritseldanu.. :(

Seda kolme asja olen ma varemgi teadnud ja praktikas kasutanud (et aru saada millised arvud jaguvad kolmega).

Ise olen avastanud selle:
1ruudus=1 +3 +2
2ruudus=4 +5 +2
3ruudus=9 +7 +2
4ruudus=16+9 +2
5ruudus=25+11+2
6ruudus=36+13+2
7ruudus=49+15
8ruudus=64
jne.
Paberil on seda lihtsam seletada
nii et kui aru ei saanud siis +3 +5 +7... märgib ruutude kasvu ning +2 +2 +2 märgib ruutude kasvude kasvu.

Kuupidega on asi keerulisem ja korrapärasus algab kuuest.

See tuleneb valemist (a+b)²=a² + 2ab + b². Pane numbrid asemele ja siis on seda sinu avastust matemaatilist ka hea seletada.

Ei!
5+5 ei ole 11 ja ei saa selleks.
Isegi kompleks ega mingide muude arvude vallas.

5 on viis ja selleks ta jääb.


Lihtne!
