You can put this solution on YOUR website!
we know that every 2pi a full circle has been completed.
\n" ); document.write( "----------
\n" ); document.write( "In terms of pi/5 a full circle is 10pi/5
\n" ); document.write( "but we need 7pi/5 more. 5pi/5 = pi = 1/2 circle
\n" ); document.write( "so we need 2pi/5 more.
\n" ); document.write( "The terminal angle is 2pi/5.
\n" ); document.write( "-----
\n" ); document.write( "In terms of pi/2 a full circle is 4pi/2
\n" ); document.write( "16 circles = 64pi/2
\n" ); document.write( "so we need 3pi/2 more.
\n" ); document.write( "The terminal angle is -pi/2.
\n" ); document.write( "-----
\n" ); document.write( "In terms of pi/9 a full circle is 18pi/9
\n" ); document.write( "but this is 3pi/9 too much, so we come back 3pi/9 = pi/3
\n" ); document.write( "The terminal angle is pi/3.
\n" ); document.write( "
\n" );
