Identify the phase shift and then sketch one complete cycle of the graph. In each case, graph y=cos(x-pi/2).

\n" ); document.write( "Equation for cos function:y=Acos(Bx-C), A=amplitude, Period=2π/B, Phase shift=C/B.
\n" ); document.write( "For given cos function:y=cos(x-pi/2)
\n" ); document.write( "amplitude=1
