What are the amplitude and midline?

Amplitude: 1; midline: y = 1
Amplitude: 0; midline: y = 0
Amplitude: 2; midline: y = 1

mjdennis · Answer

Amplitude is half the difference between highest and lowest value.$$\frac{ (y _{_{HI}} - y _{LO}) }{ 2 }$$

vladthepro · Answer

so it would be 1?

mjdennis · Answer

I'm here to help.  What is the maximum y?  What is the minimum?  What happens when you subtract and divide by two?

vladthepro · Answer

it will equal 2

mjdennis · Answer

("Y" is the up-and-down direction, if that is your difficulty)

vladthepro · Answer

brb

mjdennis · Answer

and half 2 is one, so that is your amplitude.

Next, midline

mjdennis · Answer

Midline is the _average_ between high and low values.
$$midline = \frac{ y_{HI} - y_{LO} }{ 2 }$$
Or, in other words, a number halfway between hi and low values.

Oh k I see how this works. Thx for ur time and help :)
