use a coterminal angle to find the exact value of the given expression
\n" ); document.write( "tan(12pi)
\n" ); document.write( "------
\n" ); document.write( "Since 2pi is once around the circle, 12pi is 6 times round the circle.
\n" ); document.write( "-----
\n" ); document.write( "tan(12pi) = tan(0) = 0
