The contents in high school:
Trigonometric functions, some basic inequalities and identities.
The contents before mid-term exam: Please review the details of them.
Chapter 2: Differentiation
Derivatives of one variable functions, derivatives of parameter functions, Chain rule of derivatives, the tangent line of the curve, L.Hospital Rule, critical points of one variable, local maximum and local minimum of one variable function.
Chapter 3: Integration
Integration by parts, Newton-Leibniz Formula, the area of the domain in the plane, the volume of the solid which is generated by a curve rotated with an axis.
Chapter 4: Series
Taylor Series and Power Series, radius of convergence of power series, the convergence domain of power series, the sum of geometric series and arithmetic series.
Chapter 5: Three Dimensional Spaces
Cross Product and Dot Product of vectors, projection of vectors, the equation of the plane and the line in 3-dimensional space, Distance from a point to a plane, Distance from a point to a line, the distance between two lines in two or three dimensional spaces, the distance between two parallel planes. Intersection points of two different curves.
The contents after mid-term exam: Must prepare them.
By the way, 2-3 questions means at least 2 questions, at most 3 questions. 0-1 question means 0 question or 1 question.
Geometric Graphs in Three Dimensional Space:
sphere with radius and center
Chapter 6: Fourier Series:
Fourier Coefficients of functions with period : 1 question. Especially, and (Integration by parts).
Fourier Coefficients of functions with period : 1 question, where is a positive real number. Especially, and (Integration by parts).
Calculate the summation of Fourier coefficients: 0-1 question. Especially, and .
Cosine and sine expansion of function on the half domain: 1 question.
Chapter 7: Function of Several Real Variables
Directional derivatives, partial derivatives, gradient of functions with two or three variables, Chain Rule of partial derivatives: 1-2 questions. (Pay attention to whether the vector is a unit vector or not. If it is not a unit vector, you should change it to a unit vector first, and then calculate the directional derivatives).
Critical points of two variable functions (saddle point, local maximum, local minimum): 0-1 question. (Calculate the partial derivatives first, then evaluate the critical points, so we can decide the property of the critical points from some rules).
Lagrange’s method: 0-1 question. (Calculate the maximum value of functions under some special conditions. Construct the function first, evaluate partial derivatives secondly, and calculate the critical points of the new functions. In addition, if you use inequality “arithmetic mean” is greater than “geometric mean”, then the question will become easier.)
Chapter 8: Multiple Integral
Double integral, polar coordinate: 1 question. (The formula of polar coordinate in the plane).
Reverse the order of integration of double integral: 1 question. (Draw the picture of domain and reverse the order of dx and dy).
Volume of the solid: 1 question. (Double integral, find the function and the domain on the plane. If the domain is a disk or a sector, then you can use the polar coordinate).
Area of the surface: 1 question. (Partial Derivatives of functions with two variables, the domain on the plane. If the domain is a disk or a sector, then you can use the polar coordinate. The area of a surface is a special case of the surface integral of a scalar field).
Triple integral: 0-1 question. (The method to calculate the triple integral is similar to double integral).
Chapter 9: Line Integrals
Length of a curve: 0-1 question. (Parameter equation of the curves. Length of a curve is a special case of line integral of a scalar field).
Line integrals of scalar fields: 1 question. (The equation of line segment, the equation of the circle with radius , the length of vectors). Geometric meaning: the area of the wall along the curve.
Line integrals of vector fields: 1 question. (The equation of line segments, the equation of the circle with radius , Dot product of vectors). Physical meaning: Work done.
Conservative vector fields and Newton-Leibniz formula of gradient vector fields: 0-1 question. (Definition of conservative vector field and its equivalent condition. When the value of a line integral of vector field is independent to the curve , where has the fixed initial point and the terminal point?).
Green’s Theorem: 1 question. (Two cases: the boundary is open; the boundary is closed. If the curve is open, you should close it by yourself.) Pay attention to the orientation, i.e. anticlockwise and left hand rule.
Chapter 10: Surface Integrals
Tangent plain of a surface: 0-1 question. (Partial derivatives, Cross product of two vectors, Normal vector of a plane)
Surface integrals of scalar fields: 1 question. (The equation of surface and the projection of the surface on the plane, Cross product of vectors, the length of vectors. Change the surface integrals of scalar fields to double integrals).

Stokes’ Theorem: 1 question. (This is a rule on line integrals of vector fields and surface integrals of vector fields. Remember the operator . Pay attention to the orientation of the curve on the boundary, i.e. the right hand rule).
Divergence Theorem: 0-1 question. (This is a rule on surface integrals of vector fields and triple integrals. Remember the operator ).
