How can 2A * Sina = (2B + C) SINB + (2C + b) sinc become 2A & # 178; = (2B + C) B + (2C + b) C

2a*sinA=(2b+c)sinB+(2c+b)sinC
According to the sine theorem:
sinA=a/(2R),sinB=b/(2R),sinC=c/(2R)
∴2a*a/(2R)=(2b+c)*b/(2R)+(2c+b)*c/(2R)
About 2R on both sides
∴2a²=(2b+c)b+(2c+b)c

On the meaning of subject and object of cognition and their expression in the process of practice

Subject is the existence corresponding to the object
Philosophically, it refers to the person who has the ability to know and practice the object, the object of practice, and the entity attached to the attribute
Object philosophy refers to the objective things outside the subject, which is the object of the subject's cognition and practice
(1) objectification of subject
It refers to the transformation of people's essential power into objects through practice
(2) subjectification of object
1. It means that the object changes from the existing form of the objective object to the factor of the subject's life structure or the factor of the subject's essence as quantity, and the object loses its objectified form and becomes a part of the subject;
2. People produce new consciousness through practical activities, which is also a manifestation of the subjectivization of objects

It is known that the complex Z satisfies the value range of | Z-6 | + | z-3i | = 3 root sign 5 and w = Z + 1-I for | w |

The complex Z satisfying | Z-6 | + | z-3i | = 3 √ 5 is on the line segment AB with a (6,0) and B (0,3i) as the endpoints, while:
|W | = | Z + 1-I | = | Z - (- 1 + I) | is the distance from point Z to point-1 + I
|w|∈[√5,5√2]
