I am trying to solve the part c of the question. I know the initial condidtions of the motion which are Xo=3 and Vo=50 my W=10 , B1=3 B2=5 and my equation is(adsbygoogle = window.adsbygoogle || []).push({});

x(t)=3cos(10t)+5sin(10t), the question is at which first times x=0 and x(2dot)=V=0,

Now, when I plot the equation on excel, I clearly see that at Xmax (Amax) V=0 at t=0.1 and when V=Vmax x=0 at around t=0.26s.

But when I want to find these times by solving the equation , I find something different.

how to solve this equation to find the first times at wich x=0 and v=0, what am I missing while solving it ?

anyhelp appreciated

thanks
