СИСТЕМА Cрочно x + y = П/2 Sinx + Siny = - √2

Formula: sinx+siny=2.sin((x+y)/2).cos ((x-y)/2)-V2=2.sin(pí/4).cos((x-y)/2-V2=2.V2/2.cos((x-y)/2)-1=cos((x-y)/2)(x-y)/2=píx-y=2.píx+y=pí/22x=2pí+pí/2, x=pí+pí/4,x=5pí/42y=pí/2-2pí,y=pí/4-pí,y=-3pí/4Korni iz interval /0,2pí/Obšče: x=5pí/4+2k.pí,y=-3pí/4+2k.pí, k=0,1,-1,2,-2,.......
