Algebra.Com's Answer #161854 by vleith(2983)![]() ![]() ![]() You can put this solution on YOUR website! You start with the 'given'. Usually you are asked, given xyz, show abc \n" ); document.write( "Take a sheet of paper and divide it vertically in half. (Draw a line down the middle top to bottom. \n" ); document.write( "On the left hand side, show each step of the proof. One the right hand side, give the 'reason' you are allowed to make that step. The reason should be a 'math rule' (like distribution, association, some theorem, etc)\r \n" ); document.write( "\n" ); document.write( "Start at the first line and state what was given on the left side. State \"Given\" on the right side. \n" ); document.write( "Then, step by step, work from the given to 'what was to be shown (abc in our example above) \n" ); document.write( "For each step on the left side, give a 'math rule' that allows you to make that step on the right side. \n" ); document.write( "When you get to the last line, say QED on the right (what was to be shown).\r \n" ); document.write( "\n" ); document.write( "I know this is too wordy. If you have a specific proof you need to show, you might want to enter than and then see how a solution looks. \n" ); document.write( " \n" ); document.write( " |
