Improved Second Derivative Test for Relative Extrema
Wu, Yan
International Journal of Mathematical Education in Science and Technology, v38 n8 p1121-1123 Dec 2007
In this note, a modified Second Derivative Test is introduced for the relative extrema of a single variable function. This improved test overcomes the difficulty of the second derivative vanishing at the critical point, while in contrast the traditional test fails for this case. A proof for this improved Second Derivative Test is presented, followed by an example. (Contains 1 figure.)
