critical e^{ln(x)+1}-5cos(3x)

critical points

e^{l n (x) + 1} - 5 cos (3 x)

x = \frac{π}{3} + \frac{arcsin ( \frac{e}{15} )}{3} + \frac{2 πn}{3}

Solution steps

e^{l n (x) + 1} - 5 cos (3 x)

Find where

f^{'} (x)

is equal to zero or undefined

x = - \frac{arcsin ( \frac{e}{15} )}{3} + \frac{2 πn}{3}, x = \frac{π}{3} + \frac{arcsin ( \frac{e}{15} )}{3} + \frac{2 πn}{3}

Identify critical points not in

f (x)

domain

Domain of

e^{l n (x) + 1} - 5 cos (3 x) : x > 0

e^{l n (x) + 1} - 5 cos (3 x)

is not defined at

x = - \frac{arcsin ( \frac{e}{15} )}{3} + \frac{2 πn}{3}

, therefore:

x = \frac{π}{3} + \frac{arcsin ( \frac{e}{15} )}{3} + \frac{2 πn}{3}

What is the critical e^{ln(x)+1}-5cos(3x) ?
The critical e^{ln(x)+1}-5cos(3x) is x= pi/3+(arcsin(e/(15)))/3+(2pin)/3
