Learning method:

Algebra has always been the focus of the exam, and functional knowledge is the most important part of algebra. If you master the concept of function, you will find the definition domain and function value of common functions, and use the undetermined coefficient method to solve the resolution function and judge the parity and monotonicity of the function.

Function focuses on the images and properties of linear function, quadratic function, exponential function and logarithmic function. Sequence is another important part of algebra. Derivative and its application is a prominent focus in the examination in recent two years. The basic strategy of review is to pay attention to operation and application.

On the basis of understanding trigonometric function and related concepts, master the transformation of trigonometric function, including the basic relationship of trigonometric function with the same angle, the inductive formula of trigonometric function, the formula of trigonometric function with two angles and its difference, and the sine, cosine and tangent formulas of double angles, and calculate and simplify them with formulas.
