V pravidelném šestiúhelníku \( ABCDEF \) na obrázku jsou vyznačeny vektory \( \overrightarrow{a} = \overrightarrow{AB} \), \( \overrightarrow{b} = \overrightarrow{BC} \), \( \overrightarrow{c} = \overrightarrow{FD} \) a \( \overrightarrow{d} = \overrightarrow{CD} \). Vyjádřete vektory \( \overrightarrow{c} \) a \( \overrightarrow{d} \) jako lineární kombinaci vektorů \( \overrightarrow{a} \) a \( \overrightarrow{b} \).
\( \overrightarrow{c} = \overrightarrow{a} + \overrightarrow{b};\ \overrightarrow{d} = \overrightarrow{b} - \overrightarrow{a} \)
\( \overrightarrow{c} = 2\overrightarrow{a} + 2\overrightarrow{b};\ \overrightarrow{d} = 2\overrightarrow{b} - 0{,}5\overrightarrow{a} \)
\( \overrightarrow{c} = 2\overrightarrow{a} + \overrightarrow{b};\ \overrightarrow{d} = \overrightarrow{b} - \overrightarrow{a} \)
\( \overrightarrow{c} = \overrightarrow{a} + \overrightarrow{b};\ \overrightarrow{d} = \overrightarrow{a} - \overrightarrow{b} \)
