Homework Statement
Determine the limit of
lim [tex]\psi[/tex][tex]\rightarrow[/tex]1 of [tex]\psi[/tex]^(1/([tex]\psi[/tex]-1))
Homework Equations
The Attempt at a Solution
Let y = [tex]\psi[/tex]^(1/([tex]\psi[/tex]-1))
ln y = ln [tex]\psi[/tex]^(1/([tex]\psi[/tex]-1))
lim [tex]\psi[/tex][tex]\rightarrow[/tex]1 ln y = lim [tex]\psi[/tex][tex]\rightarrow[/tex]1 of (1/([tex]\psi[/tex]-1)) (ln [tex]\psi[/tex])
Differentiate
lim [tex]\psi[/tex][tex]\rightarrow[/tex]1 ln y = -1/([tex]\psi[/tex]-1)2 x (1/[tex]\psi[/tex])
lim [tex]\psi[/tex][tex]\rightarrow[/tex]1 ln y = 2/([tex]\psi[/tex]3+3[tex]\psi[/tex]2+3[tex]\psi[/tex]+1)
ln y =1/4
y = e1/4
Does e1/4 = e?
