Examination content:

1, solid geometry (1), proof: vertical (multi-plane vertical), parallel (2), solution: mainly included angle, including line plane angle and plane angle.

This part of knowledge is more difficult, for example, an angle is actually an acute angle, but what is shown in the picture is an obtuse angle, etc., which requires students to have a strong three-dimensional sense. This part of the knowledge college entrance examination accounts for 22-27 points.

2. Linear equation: there is no separate proposition in the college entrance examination, but it is easy to combine with conic curve.

3. Cyclic equation.

1, preliminary algorithm: required content of college entrance examination, 2, statistics: 3, probability: required content of college entrance examination.

The origin of mathematics:

Mathematics [English: Mathematics, derived from the ancient Greek μ θ η μ α (má th ē ma); Often abbreviated as math or maths], it is a discipline that studies concepts such as quantity, structure, change, space and information.

Mathematics is a universal means for human beings to strictly describe the abstract structure and mode of things, and can be applied to any problem in the real world. All mathematical objects are artificially defined in essence. In this sense, mathematics belongs to formal science, not natural science. Different mathematicians and philosophers have a series of views on the exact scope and definition of mathematics.

Mathematics plays an irreplaceable role in the development of human history and social life, and it is also an indispensable basic tool for studying and studying modern science and technology.
