critical sin(x)-cos(x)

critical points

sin (x) - cos (x)

x = \frac{3 π}{4} + 2 πn, x = \frac{7 π}{4} + 2 πn

Solution steps

sin (x) - cos (x)

Find where

f^{'} (x)

is equal to zero or undefined

x = \frac{3 π}{4} + 2 πn, x = \frac{7 π}{4} + 2 πn

Identify critical points not in

f (x)

domain

Domain of

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

All critical points are in domain

x = \frac{3 π}{4} + 2 πn, x = \frac{7 π}{4} + 2 πn

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

\frac{1}{2 x - 4} + 1

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

f (x) = 3 x (4 - x)^{3}

f (x) = \frac{( 4 x + 3 )}{7}
