Question
1. Consider a uniform rectangular plate (0Sr<4, 0SYS2). Its edges at x=0, x=4, and y=2 are
insulated. The edge y=2 is kept at 10°C. The steady state temperature u(x,y) satisfies the
Laplace's equation:
a?u , a?u
+
= 0
subject to the boundary conditions
u:(0,y)=0, u:(4,y)=0, 0<y<2
и,(х,0)-0, и(х,2)-Fx), 0<x <4
where the function f(x)=10 for 0<x <4.
Use
the method
of separation of variables
to
find
the steady state temperature
u(x,y) for 0<x <4 and 0<y <2.
