what is point of inflexion in mathematics. The concept of the inflection point comes from mathematics. Informally it is a point where the function stops increasing or decreasing hence the name.
You can use the derivatives or higher if you want determine whether point is maximum or minimum or saddle point or just a point of inflection. An inflection point is a point on a curve at which the sign of the curvature ie. In that case the point x _ 0 f x _ 0 is called a point of inflection on the graph of the function ie.
For example to find the inflection points of one would take the the derivative.
In other words the graph gets steeper and steeper. It means that the function changes from concave down to concave up or vice versa. The graph is concave down on the left side of the inflection point. In that case the point x _ 0 f x _ 0 is called a point of inflection on the graph of the function ie.
