Puntos de flexiones
Hallemos los puntos de flexiones, para eso hay que resolver la ecuación
$$\frac{d^{2}}{d t^{2}} f{\left(t \right)} = 0$$
(la segunda derivada es igual a cero),
las raíces de la ecuación obtenida serán los puntos de flexión para el gráfico de la función indicado:
$$\frac{d^{2}}{d t^{2}} f{\left(t \right)} = $$
segunda derivada
$$\frac{48 t e^{2 t} - 8 e^{2 t} - 7 \sqrt{2} \sin{\left(\sqrt{2} t \right)} - 100 \cos{\left(\sqrt{2} t \right)}}{9} = 0$$
