comment Show that f is surjective
@ThePhysicsStudent It's the definition of surjectivity! You have to be able to map to every element of $\mathscr{P}(A) \times \mathscr{P}(B)$, right? Well would you agree that $(A_1, \emptyset) \in \mathscr{P}(A) \times \mathscr{P}(B)$ for some $A_1$?

comment if [a,b] is a subset of(c,d) what relationships exist between a,c and b,d?
Is this a homework question? Some context would be helpful.

Do you mean $c<a<b<d$? You'll have to specify.

comment Show that f is surjective
@Imperial I think he means $A$ and $B$ are sets and $P(E) = 2^E$ the power set.

I was trying to let him get the intermediate steps on his own...

comment Differentiation Commute with Lebesgue Integration
@user251257 Which is precisely my question... I'm taking measure theory this fall, so I don't yet know about the Lebesgue dominating-type theorems.
