Tole je pa za nekoga, ki malo bolje obvlada matematiko kot jaz, v kateri sem bolj kot ne izgubljen.
Kako se nariše krivulja X - X2 , se pravi X minus X na kvadrat.
Če bi lahko dal slikco. Lahko je tudi iz slikarja. Glavno, da vidim, da je približno.
Hvala

Ena matematična
THE GOLDEN YEARS have come at last - I cannot see, I cannot pee, I cannot chew, I cannot screw, My memory shrinks, my hearing stinks, No sense of smell, I look like hell! My body's drooping, got trouble pooping. The golden years have come at last... THE GOLDEN YEARS CAN KISS MY ASS!

takle je narisano za silo v excelu. matlaba zal niam instaliranga, k sm na tesnem s placom...
drgac pa princip je tak, da je to
-x^2 (dol obrnjen U), ki ima ekstrem v tocki (0,0) in seka tocki (-1,-1) ter (1,-1),
ki ji pristejes simetralo lihih kvadrantov (x), torej premici, ki gre recimo cez tocke (-5,-5), (-4,-4), (-3,-3), (-2,-2), ... in tako naprej, seveda za vsak x, ki je element realnih stevil.
aja.. pa graf je verjetn mal svoh
p.s. aja.. pa ko -x^2 pristejes x, se maksimum prestavi v tocko (0.5,0.25) ce se ne motim, pa absciso, torej x os, seka v (0,0) ter (1,0)
I can see dumb people...They're all around us... Look, they're even on this forum!
