V krychli o délce hrany \( 1 \) jsou vyznačeny vektory \( \overrightarrow{u} \), \( \overrightarrow{v}\), \( \overrightarrow{w} \), \( \overrightarrow{z} \). Vypočtěte skalární součiny:
\[ \overrightarrow{v}\cdot\overrightarrow{z}\text{ ,}\ \ \overrightarrow{u}\cdot\overrightarrow{v} \text{ ,}\ \ \overrightarrow{w}\cdot\overrightarrow{u} \]
\( \overrightarrow{v}\cdot\overrightarrow{z}=1 \), \( \overrightarrow{u}\cdot\overrightarrow{v}=0 \), \( \overrightarrow{w}\cdot\overrightarrow{u}=1 \)
\( \overrightarrow{v}\cdot\overrightarrow{z}=\frac{\sqrt2}2 \), \( \overrightarrow{u}\cdot\overrightarrow{v}=1 \), \( \overrightarrow{w}\cdot\overrightarrow{u}=\sqrt3 \)
\( \overrightarrow{v}\cdot\overrightarrow{z}=\sqrt2 \), \( \overrightarrow{u}\cdot\overrightarrow{v}=0 \), \( \overrightarrow{w}\cdot\overrightarrow{u}=1 \)
\( \overrightarrow{v}\cdot\overrightarrow{z}=1 \), \( \overrightarrow{u}\cdot\overrightarrow{v}=1 \), \( \overrightarrow{w}\cdot\overrightarrow{u}=\sqrt3 \)
