So, it looks like we’ve got the following intervals of concavity. ... The third part of the second derivative test is important to notice. If the second derivative is zero then the critical point can be anything. Below are the graphs of three functions all of which have a critical point at , the second derivative of...

Points of Inflection: Points of inflection are points located on a graph at which the concavity of that graph changes. To find points of inflection, you set the second derivative of the particular graph equal to zero. ... THEOREM 3.9 Second Derivative Test...

To find the points of inflection, take the second derivative, which is f''(x)=-2cos(x+"pi"/4), and set it equal to zero. You find that it equals zero at the points 5"pi"/4 and 9"pi"/4. Again make a number line showing the zeros of f''(x)... ... Back to Second Derivative Test...

Concavity and the Second Derivative Test; If y = f(x) is a function, the second derivative of y (or of f) is the derivative of the first derivative. Notation: d2y dx2 , d2f dx2 , y′′, f′′. Thus, d2y dx2 = d dx dy dx. Example.

If f(x) has a tangent line at (c, f(c)), the point is called a point of inflection if the concavity of f(c) changes from upward to downward (or visa versa) at that point. ... If f "(c) = 0, then the test fails...
