(Enter none or a pair or list of pairs, e.g., if a is at an angle less than pi/2 from b and c, enter (a, b), (a, c).) (d) Have an angle of more than 7 /2 between them? (Enter none or a pair or list of pairs, e.g., if a is at an angle greater than pil2 from b and c, enter (a, b), (a,c).) Note: You can earn partial credit on this problem.
