LA: Tekoča »nagradna« domača naloga

  1. Naj bo \vec a\in\mathbb R^3 poljuben neničelni vektor in \mathcal B_{\vec a}:\mathbb R^3\to\mathbb R^3 linearna preslikava, ki vektor \vec x\in\mathbb R^3 pošlje v \mathcal B_{\vec a}(\vec x)=\vec a\times\vec x. Poišči {\rm im}\,\mathcal B.
  2. Ohranimo oznake iz točke 1. Za vektorja \vec a,\vec b\in\mathbb R^3 čim lepše zapiši \mathcal B_{\vec b}\circ\mathcal B_{\vec a}.
