You can put this solution on YOUR website!
sin(x-y)cos(y)+cos(x-y)sin(y)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "sin( (x-y) + y) ... See note below\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "sin(x - y + y)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "sin(x)\r
