(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I want to show that the partials exist for a certain function.

2. Relevant equations

My book says that if a functionfis differentiable at a pointxthen the partial derivatives exist.

3. The attempt at a solution

Rather than showing f is differentiable, I am curious if it is sufficient to just use the limit definition of a partial derivative and show that the limit exists?

Thank you for your time.
