You can put this solution on YOUR website!
This is like:
\n" ); document.write( "What breed is the dog owned by the owner of the dog who is a Pekinese?
\n" ); document.write( "It reads:
\n" ); document.write( "The angle whose Sin is the Sin(-7pi/6)
\n" ); document.write( "It remains to show that $\"+-7%2Api%2F6+=+pi%2F6+\"$
\n" ); document.write( " $\"+-6%2Api%2F6+=+-pi+\"$
\n" ); document.write( "Now going $\"-pi%2F6\"$ radians more, I get a positive $\"+5%2Api%2F6+\"$
\n" ); document.write( "The Sin of this is positive, so I guess you can say it's the same
\n" ); document.write( "as an angle of $\"+pi%2F6+\"$ . I sort of question it, but maybe it's
\n" ); document.write( "OK. Why isn't $\"5%2Api%2F6\"$ a better answer? \n" ); document.write( "

\n" );
