Find the limit of f as or show that the limit does not exist. Consider converting the function to polar coordinates to make finding the limit easier. f(x, y)

Step-by-step explanation:

Given

Required

becomes

Multiply by 1

Express 1 as

So, the expression becomes:

Rewrite as:

In limits:

So, we have:

Convert to polar coordinates; such that:

So, we have:

Expand

Factor out

Cancel out

Express as

So:

In trigonometry:

So, we have:

Evaluate the limits by substituting 0 for r

Since the denominator is non-zero; Then, the expression becomes 0 i.e.

So,

so what is the question
