\n" ); document.write( "Put each equation in standard form:

\r\n" );
document.write( "y=(a)(sin(b(x-c)))+d
\r\n" );
document.write( "amplitude: a\r\n" );
document.write( "period: (2pi)/b\r\n" );
document.write( "phase shift (horizontal shift): c\r\n" );
document.write( "vertical shift: d
\r\n" );
document.write( "1. y=(1/4)sin(2x)  -->  y=(1/4)(sin(2(x-0)))+0  a=1/4; b=2; c=0; d=0
\r\n" );
document.write( "or y=(a)(cos(b(x-c)))+d
\r\n" );
document.write( "2. y=cos(2x)-5  -->  y=(1)(cos(2(x-0)))+(-5) a=1; b=2; c=0; d=-5

\n" ); document.write( " \n" ); document.write( "
