critical f(x)=3sin(x)+3cos(x)

critical points

f (x) = 3 sin (x) + 3 cos (x)

x = \frac{π}{4} + 2 πn, x = \frac{5 π}{4} + 2 πn

Solution steps

3 sin (x) + 3 cos (x)

Find where

f^{'} (x)

is equal to zero or undefined

x = \frac{π}{4} + 2 πn, x = \frac{5 π}{4} + 2 πn

Identify critical points not in

f (x)

domain

Domain of

3 sin (x) + 3 cos (x) : - \infty < x < \infty

All critical points are in domain

x = \frac{π}{4} + 2 πn, x = \frac{5 π}{4} + 2 πn

f (x) = \frac{x}{ln ( x )}

y = - x^{2} - 6 x - 7

f (x) = 7 + (2 + x)^{\frac{1}{2}}

\frac{x}{x - 1}

f (x) = \frac{1}{x ^{2}} - 2
