Please explain steps in as much detail as you can.

|A plane - wall element in a nuclear reactor has each surface maintained at a constanttemperature . At time zero a neutron flux bombards one face and causes thermalgeneration to begin within the wall . The generation rate decreases exponentially withdistance into the wall . The surface temperatures are held constant for all time . Themathematical model is :"Kit` + 8 "|" exp ( - aux ) = pot.1 ( 0, 0 ) = + ( [ , 0 ) = 1 (`, 0 ) = 1 ( 0)Determine + ( x , Q ).
