POmocy co mam dalej z tym zrobic?? Sosna: Ekstrema lokalne, co dalej f'x = 3x²−6x−6y−36 f'y = 2y−6x+24 f"xx = 6x−6 f"xy = −6 f"yx = −6 f"yy=2 3x²−6x−6y−36=0 /:3 2y−6x+24=0 /:2 x²−2x−2y−12=0 y−3x+12=0 y=3x−12 x²−2x−2(3x−12)−12=0 x²−8x+12=0 Δ=64−48=16 √Δ=4 x₁=2 x₂=6

Sosna: f(x,y)=x3−3x2+y2−6xy−36x+24y+37
