Niech \(\displaystyle{ U=\Lin\left[\left(t,0,1,1\right),\left(-1,1,2,1\right),\left(1,t,4,3\right)\right]}\),
\(\displaystyle{ W:x_{1} + sx_{2} + 3x_{3} -4x_{4} = \frac{2}{10} x_{1} + 2x_{2} -4x_{3} + 5x_{4} =0}\)
Dla jakich wartosci parametrow s,t zachodzi \(\displaystyle{ \RR^4 = U \oplus W}\). Bardzo prosze o pomoc
