du/dt=k^2 d^2u/dx^2
b.c
du/dx(o,t)=-qo
i.c
u(x,0)=0
can anyone please tell me what U(o,s)
U(o,s)=integral bwteen o to infinity of du/dx(o,t)e^-st dt
the reason i asked is if
du/dt=k^2 d^2u/dx^2
b.c
u(0,t)=-qo
i.c
u(x,0)=0
U(o,s)=integral bwteen o to infinity of u(o,t)e^-st dt = -qo/s
b.c
du/dx(o,t)=-qo
i.c
u(x,0)=0
