You can put this solution on YOUR website!
y= 3cos(2 pix + 4pi)
\n" ); document.write( "Equation of cos function:
\n" ); document.write( "y=Acos(Bx-C), A=amplitude, period=2π/B, phase shift=C/B
\n" ); document.write( "For given cos function:
\n" ); document.write( "y=3cos(2πx+4π)
\n" ); document.write( "amplitude=3
\n" ); document.write( "B=2π
\n" ); document.write( "period=2π/B=2π/2π=1
\n" ); document.write( "phase shift: C/B=4π/2π=2 (shift to the left) \n" ); document.write( "

\n" );
