My lamda value is 4.
What I have managed to get so far is:
dV/dx=-F
V=8/arctan(x/3)dx /=integrate sign!
integrate by parts
u=arctan(x/3), dv=dx
du=3/9+x^2dx, v=x
V=8/arctan(x/3)dx = 8[x.arctan(x/3)-/3x/9+x^2dx]
V= 8[x.arctan(x/3)-3/2log(9+x^2)+C]
Since V(0)=0
V= 8[x.arctan(x/3)-3/2log(9+x^2)+3/2log(9)]
V= 8[x.arctan(x/3)+3/2log(9/9+x^2)]
Not sure if this is correct, or where to go from here? Please help!
