No. Suppose I say that \"+3x+=+phi+\"
\n" ); document.write( "\"+sin%28+phi+%29+=+3+\"
\n" ); document.write( "This is impossible because the sine function
\n" ); document.write( "varies from -1 to +1
\n" ); document.write( "--------------------------------------------
\n" ); document.write( "Also, the sine function is a ratio, call it
\n" ); document.write( "\"+a%2Fh+\" . Whatever units you may assign
\n" ); document.write( "to \"+a+\" and \"+h+\", they cancel out in the ratio,
\n" ); document.write( "so it's just a number
\n" ); document.write( "
\n" ); document.write( "
\n" );
