Algebra.Com's Answer #291207 by sudhanshu_kmr(1152) You can put this solution on YOUR website! \n" ); document.write( " according to rule, tan@ = sin@/ cost@\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "so, sin40/co40 = tan40\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "tan40 - sin40/cos40 \r \n" ); document.write( "\n" ); document.write( "= tan40 -tan40\r \n" ); document.write( "\n" ); document.write( "= 0\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
