# Linearni strel --- Uvod ---

To je vaja o učinkovanju linearnih transformacij na točke v ravnini. Naj bo $M=\left(\begin{array}{cc}a& b\\ c& d\\ \end{array}\right)$ 2×2 matrika, ki določa linearno transformacijo prostora ${ℝ}^{2}$. Če točko predstavimo s stolpcem $p=\left(\begin{array}{c}x\\ y\end{array}\right)\in {ℝ}^{2}$, je torej njena slika stolpec $q=Mp=\left(\begin{array}{c}ax+by\\ cx+dy\end{array}\right)$.

Pri vaji sta podana matrika $M$ in graf z označeno točko v ravnini. Določiti morate sliko te točke in nanjo klikniti z miško. Po nekaj zaporednih poskusih boste dobili oceno natančnosti vaših strelov.

Izberite stopnjo zahtevnosti : 1 , 2 , 3 , 4 , 5 , 6 , 7 .
