You can put this solution on YOUR website!
$\"+y+=+3+-+cos%28+2x+%29+\"$
\n" ); document.write( "The max value is when the cos function is -1
\n" ); document.write( " $\"+cos%28+2x+%29+=+-1+\"$
\n" ); document.write( " $\"+2x+=+pi+\"$
\n" ); document.write( " $\"+x+=+pi%2F2+\"$
\n" ); document.write( "(B) is the answer
