f(2ec z
tan z – 6z*)dz =.
tan z + zº + c
sec z + z° +c
sec z - z°+e
- secz -z+ c
- secz+ +c
Use second derivative test, If f(=) -
9z +9 then f(=) has a local maximum at the point
z-3
Let / be a continuous function over an interval I containing a critical point e and / is differentiable over I, except possibly at point a
If f' changes sign from positive when z <e to negative when z>e, then f(c) is
neither a local maimum nor a local minimum of
local maximum of /
Son
f is concave down
f is concave up
local minimum of f
