Hi,
I should Show the following:
D is subset of R^2 with the triangle (0,0),(1,0),(0,1). g is steady.
Integral_D g(x+y) dL^2(x,y)=Integral_0^1 g(t)*t*dt
my ansatz:
Integral_0^1(Integral_0^(1-x) g(x+y) dy) dx
With Substitution t=x+y
Integral_0^1(Integral_x^1 g(t) dt) dx
But now i don't Have any ideas how to go on:-(
