(ii) Weddle's and Simpsons 3/8 "' formuras (iii) Modified Luler's and Runge kutta 3nd  order methods. 12)C Gmsider a lomegeneous boundary value problem of one dimensional unsteady state heat conduelion for a slab in 0≤x≤L. Initially the slab is at a temperature T=f(x) with thermal dificisivity a and for time 1>0 the boundary surface at x=0 is kept insulated while the houmdary at x=1 dissipates heat by convection with a heat transfer coefficient h into a medium at zero temperature. There is no heat generation in the medium. Wile the governimg ougation and boundary \& initial conditions of this problem with neat heleli and solve if by the ethed of separation of variables?
