Unformatted text preview: the function which gives the amount of salt in the tank at time t . 5. Use the eigenvalue/egenvector method to nd the general solution to the system x 1 = 3 x 14 x 2 x 2 =2 x 1 + 5 x 2 . 6. A 3foot long rod is made from a mysterious substance from Uranus, which has thermal diusivity constant 2 = 2. The initial temperature in the rod is given by 4 x for 0 x 3. Both ends of the rod are held at 0 degrees C. Write the BVP whose solution u ( x,t ) gives the temperature in the rod at point x and time t , and then solve it. (Give the rst 4 nonzero terms of the solution.)...
