$$$\frac{e^{- 2 t}}{2}\cdot \left\langle 2 e^{2 t}, 0\right\rangle$$$
Tu entrada
Calcular $$$\frac{e^{- 2 t}}{2}\cdot \left\langle 2 e^{2 t}, 0\right\rangle$$$.
Solución
Multiplica cada coordenada del vector por el escalar:
$$${\color{OrangeRed}\left(\frac{e^{- 2 t}}{2}\right)}\cdot \left\langle 2 e^{2 t}, 0\right\rangle = \left\langle {\color{OrangeRed}\left(\frac{e^{- 2 t}}{2}\right)}\cdot \left(2 e^{2 t}\right), {\color{OrangeRed}\left(\frac{e^{- 2 t}}{2}\right)}\cdot \left(0\right)\right\rangle = \left\langle 1, 0\right\rangle$$$
Respuesta
$$$\frac{e^{- 2 t}}{2}\cdot \left\langle 2 e^{2 t}, 0\right\rangle = \left\langle 1, 0\right\rangle$$$A
