Algebra.Com's Answer #396884 by Theo(13342)![]() ![]() You can put this solution on YOUR website! your truth table is shown below: \n" ); document.write( " \r\n" ); document.write( " p q ~q (p^~q) q <-> (p^~q)\r\n" ); document.write( "\r\n" ); document.write( " T T F F F\r\n" ); document.write( " T F T T F\r\n" ); document.write( " F T F F F\r\n" ); document.write( " F F T F T\r\n" ); document.write( " \n" ); document.write( "you have 2 variables so there will be 2*2 = 4 rows \n" ); document.write( "p and q have 4 possible variations. \n" ); document.write( "they are TT TF FT FF \n" ); document.write( "those options are shown in columns 1 and 2. \n" ); document.write( "if q is true, then ~q is false. \n" ); document.write( "if q is false, then ~q is true \n" ); document.write( "that fact is shown in the third column. \n" ); document.write( "(p^~q is true if both p and ~q are true, otherwise it is false. \n" ); document.write( "that's shown in the fourth column. \n" ); document.write( "q <-> (p^~q) is true if they both agree (either TT or FF). \n" ); document.write( "Otherwise it is false. \n" ); document.write( "<-> symbol is if and only if condition . \n" ); document.write( "-> symbol is if then condition. \n" ); document.write( "~ means not \n" ); document.write( "T means true \n" ); document.write( "F means false \n" ); document.write( "here's a lesson written by yours truly a while ago. \n" ); document.write( "it should still be valid. \n" ); document.write( "http://www.algebra.com/algebra/homework/Conjunction/THEO-2011-08-19.lesson \n" ); document.write( "i'd give you more references but i ran out of time and have to go. \n" ); document.write( " \n" ); document.write( " |
