Question

Copper wire coated insulating materials on its surface is assumed perfectly insulated laterally. Thus heat in the wire flows in x-direction only. In this case the temperature of the wire can be modeled by 1-D heat equation: =c ends (x-0 and x-L) of the wire are also insuiated for all time and initially temperature distribution of the wire can be modeled by /() Please derive u(x,t) of the copper wire. (15 points) b. If f(x) cos(x). piease tind temperature distribution of the wire at K(x..-Ox) OHNter t10 the wire's two ends are immediately contact to a thermal eservoir with temperature 0. please find the temperature distribution of t-10. (5 points) ve wire atter t-10. (5 points)
