WebFeb 3, 2024 · Ans.1 We find the points of inflection by finding the points x at which $f”(x)=0$.This will give us the candidates for the point of inflection, say x=a,b. Then we do the concavity test to check if the concavity of the graph changes across these points. WebDefinition. Inflection points in differential geometry are the points of the curve where the curvature changes its sign.. For example, the graph of the differentiable function has an inflection point at (x, f(x)) if and only if its first derivative f' has an isolated extremum at x. (this is not the same as saying that f has an extremum). That is, in some neighborhood, x … WebJan 22, 2015 · One idea would be to smooth the data by taking moving averages or splines or something and then take the second derivative and look for when it changes sign. This would find approximate "inflection points" or "turning points" -- literally, it would find when the concavity changes.
