Find the limit of f as (x , y) → (0 ,0 )or show that the limit does not exist. Consider converting the function to polar coordinates to make finding the limit easier.
f(x , y) = (x³ - xy²)/ (x² + y²)

As suggested, let's use polar coordinates:

To get

We can simplify the expression to

And simplify to get

So, as , as well.

the answer is mp

step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
