Draw the graph of the function: g(x)= -cos(x/3)/3
\n" ); document.write( "Equation for graphing cos function: y=Asin(Bx-C), A=amplitude, Period=2π/B, Phase-shift=C/B
\n" ); document.write( "For given function: g(x)= -cos(x/3)/3=(-1/3)cos(x/3)
\n" ); document.write( "Amplitude=-1/3 (basic cos curve reflected around the x-axis)
\n" ); document.write( "B=1/3
\n" ); document.write( "Period=2π/B=2π/(1/3)=6π≈18.85
\n" ); document.write( "Phase-shift: none
\n" ); document.write( "see graph below as a visual check:\r
