WebInflection points are found in a way similar to how we find extremum points. However, instead of looking for points where the derivative changes its sign, we are looking for points where the second derivative changes its sign. Let's find, for example, the inflection … WebWhich you believe depends on the definition you employ. If you claim that for a point of inflection the tangent line there must eventually cross the x axis, then you're implicitly speaking to its differentiability, and you're in the Spivak camp. If you say that an inflection point merely requires that concavity changes across a point then you ...
