$\"+7%2Api%2F4+\"$
\n" ); document.write( "--------------
\n" ); document.write( "Note that this angle is just $\"+pi%2F4+\"$
\n" ); document.write( "short of being $\"+8%2Api%2F4+\"$ , which is
\n" ); document.write( " $\"+2%2Api+\"$ , a completed circle.
\n" ); document.write( "------------------------------
\n" ); document.write( "So, $\"+7%2Api%2F4+\"$ is in the 4th quadrant, and
\n" ); document.write( "makes an angle of $\"+-pi%2F4+\"$ with the
\n" ); document.write( " $\"0\"$ radian reference
\n" ); document.write( "-----------------------
\n" ); document.write( "The tan is negative in the 4th quadrant
\n" ); document.write( " $\"+tan%28+-pi%2F4+%29+=+-1+\"$
\n" ); document.write( " \n" ); document.write( "
