Definition and value domain

Monotonicity and parity

Inverse function and derivative function

Maximum and extreme value

2. Exponential and logarithmic functions (intermediate difficulty)

Refers to the logarithmic function algorithm (for example, what is the 0 th power of a and what is lg 1).

Refers to the image attribute of logarithmic function (function increase or decrease, function value judgment)

3, trigonometric function (the score of this question is 12-30 points, the formula is examined more, and students need to memorize and recite more parts, so it will be much easier to remember the formula and do the problem).

Inductive formula

Flexible use of the sum and difference formula of 1

Auxiliary angle formula, minimum positive period

Solving triangles (sine theorem, cosine theorem)

4, series (two questions in the general exam, first-class difference, first-class ratio. The difficulty is moderate. Students often become arithmetic progression, and sometimes they take a big exam, with a score of 6-24).

5, straight lines and equations (formula problem, the difficulty is not high)

Tilt equation (slope and intercept)

Point to line equation, line to line equation, line to line equation

6. Circle sum equation (the difficulty is easy, the question type can be large or small, and the score is high or low)

General equation and standard equation of circle (determination of center and radius)

Comprehensive investigation of straight line and circle

7. Conic curve (most standard equations are rote)

Elliptic equation (focus, eccentricity, major axis and minor axis, geometric properties)

Hyperbola (focus, eccentricity, imaginary axis, asymptote, geometric characteristics)

Parabola (focus, eccentricity, directrix, focal length and geometric characteristics)
