Anonymous users2024-02-06Why can top students get high scores without much effort when studying and taking exams? Is it because they have different talents than we do? Or is it not the same IQ as ours?
Neither! Let's master the following 3 methods and use them flexibly, so that it will not be so difficult to get a high score.
1.Mnemonics.
Attention is the door to memory, and if you meditate for more than 10 minutes every day, your memory will be significantly improved. You can also eat more nuts.
2.Mind mapping.
Mind mapping is to use the form and network structure of **, plus keywords and images, to express the whole book on a piece of paper. When children are reviewing, they only need to look at the mind map to memorize the content of the entire book. This can also improve your child's self-confidence and interest in learning.
3。Quick read.
For the improvement of composition, then reading a lot of classic books is a must. The reading speed of ordinary people is generally about 300 words a minute, as long as you master the skills and methods of fast reading, it is very easy to have 1,000 words a minute. 1.
Increase the number of words in each paragraph, 2Reduce the time spent reading each paragraph,3 and reduce the number of times your gaze moves back to the previous sentence. These have to be practiced repeatedly to improve.

Anonymous users2024-02-05(1) Proof: Connect the OD
e is a point on the circle o and ac is the diameter.
So AEC=90°
So bec=90°
Because d is the midpoint on BC.
So ed=1 2 * bc = dc
Because oe=oc, od=od
The triangle OED is all equal to the OCD
So oed= ocb=90°
So de is the tangent of the circle o.
2) I don't know if you have learned the projection theorem or not, if you learn it, you can write ae*be = ce2, if you don't learn it, the similarity is over: AEC and CEB two triangles.
Let ae=x, then be=2x
For right-angled triangle BEC, BE2 + CE2 = BC2
Substituting yields: be2+ae*be=ac2
4x2+2x2 = 6*6
The solution is x = root number 6
ae = root number 6

Anonymous users2024-02-04The integer part of 13 to the 3rd power is 2, because the 3rd side of 2 is 8 and the 3rd side of 3 is 27
The decimal part of the root number 13 is not easy to find, you can first find it as the integer part is 3 (because the square of 3 is 9, and the square of 4 is 16), so the decimal part of the root number 13 is the root number 13 -3, so m-n=5 - the root number 13
Xueba", the original meaning of "villain in the academic world", Internet term refers to a type of person who usually studies hard, studies seriously, has rich knowledge, and has outstanding academic achievements.

As we all know, China has always been a relatively traditional country with relatively conservative thinking. But with the high development of society, people's thinking is different from before. Many people's concept of emotional life has also changed, which is really different from the thinking of Chinese people in the past. >>>More
Personally, in school is to improve knowledge, test scores; Life is to make your life better, you don't want to be cheated on buying things, right? Don't want to be fooled, do you? Math can prevent this. To put it more broadly, it is to contribute to mankind and promote the development of society, haha!
