I need to find the amplitude, period, and phase shift. Then graph one period of the function. y=1/2sin(x+pi)
\n" ); document.write( "**
\n" ); document.write( "Equation for graphing sin functions: y=Asin(Bx-C), A=amplitude, Period=2π9/B, Phase-shift (C/B)
\n" ); document.write( "For given function: y=1/2sin(x+pi)
\n" ); document.write( "Amplitude=1/2
\n" ); document.write( "B=1
\n" ); document.write( "period=2π/B=2π/1=2π
\n" ); document.write( "1/4 period=2π/4=π/2
\n" ); document.write( "Phase shift = C/B=π/1=π (shift to the left)
\n" ); document.write( "..
\n" ); document.write( "Graphing the function on a (x,y) coordinate system with the x-axis scaled in radians\"
\n" ); document.write( "For one period:
\n" ); document.write( "Coordinates for basic sin function: (0,0), (π/2,1), (π,0), (3π/2,-1),(2π/0)
\n" ); document.write( "Multiply y-coordinates by (1/2) : (0,0), (π/2,1/2), (π,0), (3π/2,-1/2), (2π/0)
\n" ); document.write( "For the final configuration: shift x-coordinates π units to the left.
\n" ); document.write( "(-π,0), (-π/2,1/2), (0,0), (π/2,-1/2), (π,0)
\n" ); document.write( "you now have the coordinates with which to plot the graph for one period \n" ); document.write( "
\n" );
