Vocaloid · Answer

I'm an idiot can you remind me what S(0) means in this context, is that the initial value

psirockin2 · Answer

I´m pretty sure S(0) is the equalibrium point?

psirockin2 · Answer

equilibrium... me no spell good

something like this? :S

@sillybilly123 @Nnesha sorry to rely on you guys so much today, I'm just out of it

psirockin2 · Answer

I don´t know... I´m just as confused

psirockin2 · Answer

Wait... the formula! s(t)=acoswt

w is omega
a is the amp
t is time...

psirockin2 · Answer

amp is the 2 inches...
period is 0.5 sec 
so 2pi/omega has to equal 0.5

4pi?

@Vocaloid 
Sorry to bug you

sillybilly123 · Answer

that's it Voca

with the subsequently added data, we have $s(t) = 2 ~ \cos \omega t $

and $\omega = \dfrac{2 \pi}{0.5} = 4 \pi$
