find the graph of the equation, and the period and phase shift.
\n" ); document.write( "y=sin(1/4x+pi/3)
\n" ); document.write( "**
\n" ); document.write( "Equation used for graphing sin functions: y=Asin(Bx-C), A=amplitude, Period=2π/B, Phase shift=C/B.
\n" ); document.write( "For given equation: y=sin(1/4x+pi/3):
\n" ); document.write( "A=1
\n" ); document.write( "B=1/4
\n" ); document.write( "Period: 2π/B=2π/(1/4)=8π
\n" ); document.write( "1/4 period=8/4=2π
\n" ); document.write( "phase shift: C/B=(π/3)/(1/4)=4π/3 (shift to the left)
\n" ); document.write( "..
\n" ); document.write( "Graph for one period:
\n" ); document.write( "scale of x-axis in radians
\n" ); document.write( "With no phase shift, (x,y) coordinates for the given sin function would be as follows:
\n" ); document.write( "(0,0), (2π,1), (4π,0), (6π,-1), (8π,0)
\n" ); document.write( "..
\n" ); document.write( "A phase shift of 4π/3 radians would shift x-coordinates to the left as follows:
\n" ); document.write( "(-4π/3,0), (2π/3,1), (8π/3,0), (14π/3,-1), (20π/3,0)
\n" ); document.write( "..
\n" ); document.write( "y-intercept

\n" ); document.write( "y=sin(π/3)
\n" ); document.write( "y=√3/2\r
\n" ); document.write( "\n" ); document.write( "You now have all the points you need including the y-intercept to plot given sin function.\r
