Picture yourself in a ’special’ world where
\n" ); document.write( "\"c%5E2%2Bs%5E2=1\"
\n" ); document.write( "Under this assumption, select the true statement/s:
\n" ); document.write( "A) Every
\n" ); document.write( "\"1+%2B+%28s%5E2%29%2F%28c%5E2%29\"

\n" ); document.write( "Edwin made a mistake in B)
\n" ); document.write( "The way I did it was:
\n" ); document.write( "We need to determine IF: \"matrix%281%2C3%2C+s%5E2%2Fc%5E2%2C+%22=%22%2C+highlight%281%5E%22%22%2Fc%5E2+-+1%29%29\"
\n" ); document.write( " ------ Substituting \"matrix%281%2C3%2C+1+-+c%5E2%2C+for%2C+s%5E2%29\"
\n" ); document.write( "
\n" ); document.write( " <====== As you can clearly see, this is TRUE! \n" ); document.write( "
\n" );
