WebSolution In Example 1, we proved that \(f\) is differentiable at \((0,0)\), by using the definition of differentiability. That was a moderate amount of work, and it only told us about the point \((0,0)\). Now let’s use Theorem 3 instead. ... But determining the directional derivatives at a point using their definition is not. For example. WebA differentiable function is always continuous, but the inverse is not necessarily true. A derivative is a shared value of 2 limits (in the definition: the limit for h>0 and h<0), and this is a point about limits that you may already know that answers your question. At points of discontinuity of f (x) the derivative, which is a shared value of ...
