Neporo4naja [7]3 years ago
8 0

Answer:

There is no manual shortcut except you're using a program like MATLAB or Mathcad.

Otherwise the process still remains the same:

1. Find the determinant |a|

2. Find the minor, then find the cofactors C

3. Find the adjoint of a which is the transpose of C

4. Find the inverse with

\frac{1}{ |a | }  \:  \times adjoint \: of \: a

When a son was born to Confucius, the king of Lu sent over a carp as present. Confucius named his son Carp.
Natalka [10]
It is ironic that Confucius's son died an early death. We can infer that the death of Confucius' son, Carp is ironic, he suffered an early death when the symbolism of the carp fish is longevity, because carps can get very old, it also represents the dragons due to big scales on the body of a carp. According to the meaning of the carp Confucius' son, Carp, should have a long live which did not happen.
