Hello, let me answer your question about how to play triangle symbols. I believe many friends still don't know the symbol Delta. Now let's have a look!

1, δ Pronunciation: δ.

2.δ has different meanings in different usages: δ bond in valence bond is called δ bond, which can be abbreviated as "face to face".

3. The δ bond has only two nodes (the plane with zero electron cloud density).

4. From the bond axis, there is no difference between the orbital symmetry of δ bond and the orbital symmetry of D orbit, and the Greek letter δ also comes from D orbit.

5.2. Denotes charged: δ-means negatively charged, and δ+means positively charged.

6.3. Names of two functions in mathematics: ① Kroneck δ.

7.② Dirac δ function.

8. Symbols deleted in proofreading.

9、? Extended data:

δ is the lowercase form of the fourth Greek letter, and the uppercase δ.

10, δ is the English word for Delta, and it is shaped like a triangle, just like a capitalized δ.

1 1, д of Cyrillic letters and d of Latin letters all come from Delta.

12, capital Δ is used to indicate the change of variables in mathematics and science. In regression analysis, the difference between the measured value (true value or accurate value) and the predicted value of regression equation is determined.
