--------------- 函数f					-- 设置原点的偏移量
-- rot is 							-- 设置旋转角度
-- scale is (1, 1);	               -- 设置横坐标和纵坐标的比例
origin is (333,350);
for T from 0 to 200 step 1 draw (t, 0);		-- 横坐标的轨迹
for T from 0 to 180 step 1 draw (0, -t);	-- 纵坐标的轨迹
for T from 0 to 150 step 1 draw (t, -t);	-- 函数f(t)=-t的轨迹
for T from 0 to 2*PI step PI/50 draw (cos(t),sin(t));
