Find the temperature u(x, t) in a bar of silver of length 10 cm and constant cross section of area 1 cm2 (density = 10.6 g/cm3, thermal conductivity =1.04 cal/(cm-sec C , specific heat = 0.056 cal /(g- C) that is perfectly insulated laterally, with ends kept at temperature 0C and initial temperature f(x) = sin (0.1x). Prepare the graph of the function from x = 0 to L and and t = 0 to 60 min. Present the 3-D plot using MATLAB
