[問題] 解偏微分方程
我要解 parabolic equation
(partial)u/(partial)t = 0.1*(partial)^2 u/(partial)x^2
boundary condition: u(0,t) = 0 , u(1,t) = 0
initial condition: u(x,0) = sin(π*x)
我輸入
DSolve[{D[u[x,t],{t,1}] = = 0.1*D[u[x,t],{t,2}],u[0,t] = = 0,u[1,t] = = 0,
u[x,0] = = Sin[Pi*x]},u[x,t],{x,t}]
結果他只是把我輸入的方程式還給我,我要修改哪邊才會讓他讀懂?
