sinx <=1 .............. (1)
\n" ); document.write( " again ,
\n" ); document.write( "sinx>= -1
\n" ); document.write( "sin^2x >= 1
\n" ); document.write( "cos^2x <= 0
\n" ); document.write( "cosz<=0 ........ (2) \r
\n" ); document.write( "\n" ); document.write( "By 1+2
\n" ); document.write( "sinx + cosx <= 1
\n" ); document.write( "therefore ,
\n" ); document.write( "sinx + cosx (max) = 1
\n" ); document.write( " \n" ); document.write( "
\n" );
