critical sec^2(x)

Solution

critical points

sec^{2} (x)

Solution

x = πn

Solution steps

sec^{2} (x)

Find where

f^{'} (x)

is equal to zero or undefined

x = πn, x = \frac{π}{2} + πn

Identify critical points not in

f (x)

domain

Domain of

sec^{2} (x) : πn \leq x < \frac{π}{2} + πn or \frac{π}{2} + πn < x < π + πn

sec^{2} (x)

is not defined at

x = \frac{π}{2} + πn

, therefore:

x = πn

Popular Examples

extreme f(x)=(x^3)/3-x^2-8x extreme points

f (x) = \frac{x ^{3}}{3} - x^{2} - 8 x

perpendicular 4x+5y=8,(4,-2)perpendicular

4 x + 5 y = 8, (4, - 2)

domain of 1/(sqrt(x^2-7x))domain

\frac{1}{x ^{2} - 7 x}

extreme f(x)=x^2e^{-x^2}extreme points

f (x) = x^{2} e^{- x^{2}}

extreme f(x)=-6x^3+9x^2+36x extreme points

f (x) = - 6 x^{3} + 9 x^{2} + 36 x
