Oblicz współrzędne wektora AB,jeżeli A=(-1,-2)i B=(3,-2) A=(21/2,-3 3/4)iB=(-3 3/4,-2 3/4)
AB=[3-(-2),-2-(-1)]=[5,-1]
AB=[-3 3/4-21/2,-2 3/4-(-3 3/4)]=[-15/4-42/4,-11/4+15/4]=[-57/4,1]
AB=[3-(-2),-2-(-1)]=[5,-1]
AB=[-3 3/4-21/2,-2 3/4-(-3 3/4)]=[-15/4-42/4,-11/4+15/4]=[-57/4,1]
A=(-1,-2)i B=(3,-2)
AB={[3-(-1)], [-2-(-2)]}=(4, 0)
A=(21/2,-3 3/4)iB=(-3 3/4,-2 3/4)
AB= {(-3¾-21/2),[-2¾-(-3¾)]}= (-14¼,1)
AB={[3-(-1)], [-2-(-2)]}=(4, 0)
A=(21/2,-3 3/4)iB=(-3 3/4,-2 3/4)
AB= {(-3¾-21/2),[-2¾-(-3¾)]}= (-14¼,1)
