Hi there,
\n" ); document.write( "The reason the 1 disappeared from the left
\n" ); document.write( "hand side, to be replaced by Pi/2
\n" ); document.write( " and the sin disappeared from the
\n" ); document.write( "right hand side was that sin^-1
\n" ); document.write( "was applied to both sides.
\n" ); document.write( "Converting 1 => Pi/2
\n" ); document.write( "sin^-1 (1) = Pi/2.
\n" ); document.write( "Hope this helps.
\n" ); document.write( ":-)
