Algebra.Com's Answer #195065 by drk(1908) ![]() 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( " |
