I was asked by my teacher "What is the curvature of a 2-D curve at an inflection point? Why?" Can someone help me with this one? I'm absolutely at a loss as how to proceed with this. Thanks.
Ok let me try again. At an inflection point is where concavity changes...... soo.... uhhmm may I have another hint?
Edit : Just thought of this but since inflection points are where the concavity changes, wouldn't it be a straight line at that inflection point so that'll mean no curvature at all?
