Find the period, vertical phase shift, horizontal phase shift and the graph
\n" ); document.write( "F(x) = 3 cos ((pi/2) - (pi)(x))
\n" ); document.write( "..
\n" ); document.write( "Form of equation for cos function: y=Acos(Bx-C)+D, A=amplitude, Period=2π/B,
\n" ); document.write( "C/B= Hor Phase shift, D=vertical phase shift
\n" ); document.write( "Rewrite given function: 3cos(-pi*x+pi/2)
\n" ); document.write( "Amplitude=3
\n" ); document.write( "B=π
\n" ); document.write( "Period=2π/B=2
\n" ); document.write( "Hor phase shift=C/B=(π/2)/π=1/2 (shift to the right)
\n" ); document.write( "Vert phase shift: none
