extreme x+sin(x)

extreme points

x + sin (x)

Saddle (π + 2 πn, π + 2 πn + sin (π + 2 πn))

Solution steps

Find the critical points:

x = π + 2 πn

Domain of

x + sin (x) : - \infty < x < \infty

Find intervals:

Increasing

: 2 πn \leq x < π + 2 πn,

Increasing

: π + 2 πn < x < 2 π + 2 πn

Plug the extreme point

x = π + 2 πn

into

x + sin (x) \Rightarrow y = π + 2 πn + sin (π + 2 πn)

Saddle (π + 2 πn, π + 2 πn + sin (π + 2 πn))
