Mathematics -65.69, the difficulty coefficient is 0.438, which is too difficult.
Mathematics II 7 1.87 The difficulty coefficient of 0.479 is slightly higher.
Mathematics ⅲ76.80 has a moderate difficulty coefficient of 0.5 12.
1, basic contents: the concept and representation of function, boundedness, monotonicity, periodicity and parity of function, and the properties and graphs of basic elementary functions of inverse function, piecewise function and implicit function. The establishment of the function relation of elementary function; Definition and properties of sequence limit and function limit. The concepts of left limit and right limit of function, infinitesimal quantity and infinitesimal quantity. The nature of infinitesimal and its relation and the comparison of infinitesimal.
Four operations of limit, two criteria for the existence of limit, monotone bounded criterion and pinch criterion are two important limits. The concept of function continuity, the types of function discontinuity points, the continuity of elementary functions, and the properties of continuous functions on closed intervals.
2. Examination requirements: Understanding the concept of function and mastering the representation of function will establish the functional relationship of application questions. Understand the boundedness, monotonicity, periodicity and parity of functions. Understand the concepts of compound function and piecewise function, and understand the concepts of inverse function and implicit function. Master the nature and graphics of basic elementary functions and understand the concept of elementary functions. Understand the concept of limit, the concept of left and right limit of function and the relationship between the existence of function limit and left and right limit.
Master the nature of limit and four arithmetic rules, master two criteria for the existence of limit, and use them to find the limit, master the method of using two important limits to find the limit, understand the concepts of infinitesimal and infinitesimal, master the comparison method of infinitesimal, find the limit with equivalent infinitesimal, understand the concept of function continuity, distinguish the types of function discontinuity points, understand the properties of continuous functions and the continuity of elementary functions, and understand the properties of continuous functions on closed intervals.
3. Postgraduate requirements: the second postgraduate entrance examination takes advanced mathematics and linear algebra. Among them, advanced mathematics accounts for 78% and linear algebra accounts for 22%. The high number part does not test vector algebra, and the number two does not test probability theory and mathematical statistics. Compared with the number one and the number three, it is much simpler. Math II is generally taken in science or engineering. Advanced mathematics includes function, limit, continuity, differential calculus of univariate function, integral calculus of univariate function, differential calculus of multivariate function and ordinary differential equation.
