**Steve**, Wednesday, October 12, 2011 at 4:47amCritical points are zeros, max,min,inflection.

zeros: g(x) = 0: lots of values, such as 0, 1.3, 4.7,... (eyeballing the graph)

max/min: g' = 0: 36 - 9sec^2 = 0

sec^2(x) = 4

sec(x) = 2

x = pi/3, 5pi/3, ...

inflection: g'' = 0: -18secx tanx = 0

where tanx = 0, or

odd multiples of pi/2
