SD.Second Derivative Test 1.The Second Derivative Test We begin by recalling the situation for twice differentiable functions f(x)of one variable. Tofind their local(or“relative”)maxima and minima,we 1.find the critical points,i.e.,the solutions of f′(x)=0;2.apply the second...

Extremas – First Derivative Test & Second Derivative Test Calculus - Santowski Calculus - Santowski 11/10/2019 1 Fast Five ? 1. Determine the first and second derivatives of the function f(x) = x4 – 4x3 + 4x2 ? 2. Determine the first and second derivatives of the function f(x) =...
apply the second derivative test to each critical point x 0 : f ′′ (x 0 ) > 0 ⇒ x 0 is a local minimum point; f ′′ (x 0 ) < 0 ⇒ x 0 is a local maximum point. The idea behind it is: at x 0 the slope f ′ (x 0 ) = 0; if f ′′ (x 0 ) > 0, ...

If, however, the function has a critical point for which f′(x) = 0 and the second derivative is negative at this point, then f has local maximum here. This technique is called Second Derivative Test for Local Extrema.Three possible situations could occur that would rule out the use of...
