Who has the road to math success must take two 2 2 1 answers.

Let's write the title, there is no such thing.

Group A: 3 (1) (3) to (2) (4) (5) False 4 (1) 2) 8 (3) 2 (4) Parallel or in plane (5) Parallel or intersecting (6) Intersecting or different planes.

5 coplanar 6 because AA'//bb' ,aa'=bb'The quadrilateral aa'bb'is a parallelogram, so ab = a'b'In the same way, bc = b'c'So, 7 3; 3

Group B 1 (1)C (2)D (3)C

All of them are available.

I found it for you, the landlord.

But that's a non-txt file.,Can't be copied.,How to copy all kinds of letter formulas for you.,I'll see if it's OK.。

。。。Wait.

Group p513(1) True (2) False (3) True (4) False (5) False 4(1) (2) 8 (3) 2 (4) parallel or in plane (5) parallel or intersecting (6) intersecting or different planes.

5.Coplanar. Am I right?

It is known that the function f(x) = (k is constant, e= is the base of the natural logarithm), and the tangent of the curve y= f(x) at the point (1, f(1)) is parallel to the x-axis.

) to find the value of k;

) to find the monotonic interval of f(x);

Let g(x)=(x2+x), where is the derivative of f(x), prov: for any x 0,.

Hello. The knowledge points of compulsory 2 are the knowledge of spatial geometry and the proof of spatial solid geometry, the equation of straight lines and the equation of circles. The knowledge points of the elective two bars and one are propositions and conic curves.

The conic curve is an extension of the equation of the straight line and the circle of the compulsory two, and the second compulsory is the foundation. Be sure to learn well Other connections are relatively few.

There is no exact comparison, both Compulsory 1 and Compulsory 2 are very important.

Compulsory 1, Chapter 1.

Sets and Functions Concepts.

1 1 Collection.

1 2 Functions and their representations.

1 3 Basic properties of functions.

Chapter 2 Basic Elementary Functions ( ).

2 1 Exponential function.

2 2 Logarithmic functions.

2 3 power functions.

Chapter 3 Application of Functions.

3 1 Functions and Equations.

3 2 Functional Models and Their Applications.

Many of the college entrance examination questions are examined by combining multiple knowledge points.

Compulsory 1 is mainly functions, which are the basis of the entire high school algebra part, and the types of questions involved account for more than 60% of the questions in the college entrance examination.

Compulsory 2 is mainly the straight lines and circles in three-dimensional geometry and plane analytic geometry, which is the basis of all geometric parts, and the questions involved can account for more than 30% in the college entrance examination.

If you have to say that you only need to examine the compulsory one question, there will be a multiple-choice question in the general set, and there will be a small question at the zero point of the function, which accounts for 10 points, and the function part must be examined, but it will definitely involve the content of the other algebra parts, and this score cannot be accurately located.

And if you have to talk about the question of the second compulsory course, the three-dimensional geometry will generally have a small problem in the three views, and there will be a big problem, accounting for 12 + 5 = 17 points, and there will generally be a small question for straight lines and circles, accounting for 5 points, a total of about 22 points.

It's hard to say, this is to see the questioner, I think the five compulsory books are very important.
