Je daný vektor \(\vec{u} = (\sqrt{3};1)\). Nájdite všetky vektory \(\vec{w}\) také, že \(\left |\vec{w}\right | = 4\) a odchýlka vektorov \(\vec{u}\), \(\vec{w}\) je \(60^{\circ }\).
\(\vec{w} = (0;4)\), \(\vec{w} = (2\sqrt{3};-2)\)
\(\vec{w} = (0;-4)\), \(\vec{w} = (\sqrt{7};-3)\)
\(\vec{w} = (0;4)\), \(\vec{w} = (\sqrt{7};3)\)
\(\vec{w} = (\sqrt{5};\sqrt{11})\), \(\vec{w} = (2\sqrt{3};-2)\)
