OpenStudy (bahrom7893):

What function?

OpenStudy (bahrom7893):

Amplitude is -2, no?

OpenStudy (bahrom7893):

Period is 4 i think.. Sorry i froze

sam (.sam.):

Yeah

OpenStudy (bahrom7893):

Amplitude = highest point that the function reaches / 2

OpenStudy (bahrom7893):

highest or lowest i meant

sam (.sam.):

I dont think you have to divide 2

OpenStudy (bahrom7893):

yea so the highest point is f(14.5) or something, but amplitude isn't f(14.5), it's only the length of the top half

OpenStudy (bahrom7893):

Oh is amplitude an absolute value? Anyway you guys can discuss this later, I gtg now, cya.

sam (.sam.):

Ok

OpenStudy (unklerhaukus):

The amplitude is the magnitude of the displacement from equilibrium. so you should get two
