\large\ANSC{\vec ANSL}

  • \large\pink{\vec b}
  • \large\green{\vec c}
  • \large\purple{\vec d}
  • \large\red{\vec e}

Leyendo del gráfico, vemos que \vec a = AX \hat\imath + AY \hat\jmath.

SA \vec a = SA \cdot (AX \hat\imath + AY \hat\jmath).

\hphantom{SA \vec a} = (SA \cdot AX) \hat\imath + (SA \cdot AY) \hat\jmath.

\hphantom{SA \vec a} = SA * AX \hat\imath + SA * AY \hat\jmath.

El vector que corresponde es \vec ANSL.
