1. Triangle-trigonometric function or solution triangle;

2. Solid geometry proof-parallel or vertical, find the volume;

3. Statistics and probability-frequency histogram and simple classical probability;

4. Series-the general formula of arithmetic progression and geometric progression, and the summation method of series focuses on calculation;

5. Derivative-study the tangent of the curve, and study the monotonicity and extreme value, maximum value and zero point of the function;
