Hello, You must have That is to say, by writing the boundaries: maybe reversing the order of integration will help : and that's all
For part (c) here would the limits be 0,inf for y and 0, 2-y for x dxdy?

Thanks, I think I might pass this exam!

I'd go one further and also pull out the , as I did below.
