The motion of a particle pertorming damped vibrations s given by \( \gamma=e^{-t} \operatorname{Sin} 2 t, \gamma \) being the displacement rom its mean position at time \( t \). Show that \( \gamma \) is a maximum when \( t=\frac{1}{2} \tan ^{-1}(2) \) and determine this maximum displacement to hree significant tigures.

The minimum value of the function \( f(x)=\frac{x}{x+1} \) is

The motion of a particle performing damped vibrations is given by \( \gamma=e^{-t} \sin 2 t, \gamma \) being the displacement trom its mean position at time \( t \). Show that \( \gamma \) is a maximum when \( t=\frac{1}{2 \tan ^{-1}(2)} \) and determine this maximum displacement to three significant figures.
