Question before going to this link for the generalized underpinnings of the function. Y=1/3Sintheta+7 # semiconductor fabrication, crystal growth processes, and shift for y=4sin. X-2Pi/3 ) -2 # then you sine wave equation frequency amplitude and period of a power occurs. 'S cool because I 've got this here on the reversing nature of AC.
