Inverse deduction problem solving is for those who can not be positive or more cumbersome topics, breaking the routine from the perspective of reverse thinking to find the key to solving the problem simply put the unknown result is pushed to the known conditions, or from the conclusion of the problem or The results to find the key conditions of the reverse push down the thinking is called reverse thinking.Reverse push law belongs to the reverse thinking of the problem-solving method.In the process of solving the problem of inverse thrust law should pay attention to the analysis of the conditions of the problem, the problem, the structure of the problem The line of reverse law is ”To know -
