The amplitude of sin(x) is 1, so we want
\n" ); document.write( " $\"sin%282x%29+=+1\"$
\n" ); document.write( "taking inverse sin, we get
\n" ); document.write( " $\"2x+=+pi%2F2\"$
\n" ); document.write( "divide by 2 and we get
\n" ); document.write( " $\"x+=+pi%2F4\"$ \n" ); document.write( "

\n" );
