Inverse function

Inverse function

1. Outline
   1. Inverse function is one of the difficulties in the first two days, and in the examination of the larger relationship, but the first two days of the test phase is very simple, and no more binding geometry
   2. The main difficulty is that the inverse function and the binding geometry
   3. Current problems are complex inverse function problems do not write process
2. Error-prone point
   1. Category talk: there are two inverse function
   2. Format: substituting principle, comparable principles
   3. Geometric meaning
      1. The basic geometric meaning

      2. AO = BO => square EFGH

      3. Diamond EFGH

      4. AO = BO => rectangle ABCD

      5. Parallelogram ABCD

      6. Rectangular: AD: BD = AE: CE

      7. Triangle: The Solution to the proportional relationship of similar triangles 

      8. Curve overlay
