# To what extent is the 2nd derivative information about the direction?

Hi community

To what extent is the 2nd derivative information about the direction?

Thanks =)

## The best answer

the first derivation are informative about the slope of the function. the second derivative provides information on the slope of the first function. f '(x) <0 then the gradient of the first derivation negative. However, one knows not whether this dissipation in the first is worth a positive negative or a zero spot. So you can not dissipation of the second really what gentleman said about the direction of the function.

here's a tip:

f (x) NEW

f '(x) 0 NEW

f "(x) 00 NEW

N = null stelle

W = turn stelle

E = extremely stelle

So for example, correspond to the zero-second derivation of turn filters of f (x)

:) to ask ?

The second derivative indicates the curvature or the rate of change of the slope.
