Given the first derivative of the continuous function y = f(x). Find y" and sketch the graph of f.
y' = tan x, -pi/2<x<pi/2
I know y"= sec2x - I need the graph and critical, inflection, and max/min points along with a picture of the graph or what need to be entered into my TI-84.
Identify the inflection points, local max and min of the function and intervals of concave up and down.
The solution determines maximum and minimum values and points of inflection.
