so the Amplitude is 4
and the period is pi
but how in the world do i get the x axis?
what do you mean by "getting the x-axis"?
I've tried everything and i'll find one way works for one type but doesn't work for another. Is it really that way? I was told to multiply pi/2 by 1/4 2/4 and 3/4 but it doesnt come out correct. Does anyone know what to add or multiply by to get the x axis? Thanks
