deadshot · Answer

@ganeshie8 Can you help me with this? I only see it as a wave bouncing off of $$-\frac{ 1 }{ 2 } and \frac{ 1 }{ 2 }$$

ganeshie8 · Answer

for period you need to look Left and Right

deadshot · Answer

It keeps hitting the 360 degree mark

deadshot · Answer

Which is

deadshot · Answer

$$2\pi$$ If I remember correctly

ganeshie8 · Answer

look at the wave from left to right,
yes one Full waveform is taking -360 to 360

ganeshie8 · Answer

$360--360 = 720$

ganeshie8 · Answer

Yes, $2\pi = 360$ is the period of normal sin wave : $\sin x$

ganeshie8 · Answer

but here  the wave is taking more time for doing one Full cycle (720) 
so, period = ?

deadshot · Answer

it takes about twice as long, so would the period be $$4\pi$$?

ganeshie8 · Answer

period is simply the time it takes for doing one Full cycle.

ganeshie8 · Answer

Yup you have it !!

deadshot · Answer

Thanks!

ganeshie8 · Answer

$720 ~ degrees = 4\pi ~radians$
