$\"%2813%2Api%29+%2F+12+=+%28%2812%2F12%2Api%29+%2B+%281%2F12%2Api%29%29+=+pi+%2B+%28pi%2F12%29\"$
\n" ); document.write( "so, the tangent = $\"tan%28pi+%2B+%28pi%2F12%29%29\"$
\n" ); document.write( "this puts the angle in the 3rd quadrant where the tangent is positive
\n" ); document.write( "the answer is:
\n" ); document.write( " $\"tan%28pi%2F12%29\"$ \n" ); document.write( "
