Need help with below problem:

The temperlm'e T of a fluid in a pipe can be modeled by the following PDE, &N a T R where # and o are constants. Isolate the time derivative of T on the left hand side. Then write the equation for the resulting right-hand-side f* using second-order central finite differences at all non-boundary mesh points i. This is the right-hand side for the resulting system of ODEs. Assume that the interval size in the spatial direction is Ax. Use only the above variable names
