Mathematical return, apagoge, counterexample method, the method of undetermined coefficient method, distribution, the overall generation into law Mathematical to various ways, but they have a unified thought, that is to have a math problem for the known and unknown change numerous for brief hard things, melt.
If the fraction equation into ZhengShi equation, the algebraic problems into geometry problems, will quadrilateral problem into a triangle, etc. Realizing this transformation method has: reduction to absurdity, counterexample method, the method of undetermined coefficient method, distribution, the overall generation into law and the static and dynamic for such by abstraction to specific transformation ideology.
不知道是不是你想要的,不过希望能帮到你.
