Find time of death of patient with differential equations

Mr. N.P. Sahani asked:

“The differential equation and solution for finding the time of death of a patient”

Answer:

See that the question is to find the time of death (Not predicting the time of death. I thought that when I read it first.)

I can give some links which will be helpful in this connection

magnetic field

Which one we should use Bio saverts law or amperes law to find a magnetic field?

chirag

Answer

Both are used to find the magnetic field .In the case  of physical magnet Biot-Savarts law can be used

In the case of a current carrying conductor Ampers circuital law is used
