For this, the first thing to do is to assume that the function of temperature with respect to r is written in one of the following ways:
Way 1:
Way 2:
To find the instant variation we must find the derivative of the temperature with respect to the distance r.
We have then:
For function 1:
Rewriting
For function 2:
Rewriting
Answer:
The instantaneous variation of the temperature with respect to r is given by:
Assuming function 1:
Assuming Function 2:
