The mathematical finale of Guangdong college entrance examination basically includes: function and derivative; Sequence; Conic curve equation; Unequal and so on. Among them, the idea of function permeates all aspects, and it can be said that function accounts for more than half of high school mathematics. Functions generally require monotonicity and can be derived; Sequence is a special function, which needs the sum of the general term formula and the first n terms; Conic curve equation generally involves straight line sum equation, chord length, midpoint and symmetry point, which can be solved by simultaneous equations and Vieta theorem. Specific analysis of specific problems, no one method can solve all the problems! If you don't understand anything, you can ask questions again! !
