Question

Use logarithmic differentiation to find the derivative of the function.
y=x1/x

Answer 1

I got
\[(x^1/x)(1/x^2lnx+1/x^2)\]
this is not right
what did i do wrong

Answer 2

[multiply every variable by xy]
y + x = xy
y - xy = - x
y(1 - x) = - x
y = - [x / (1 - x)]
y = - x / (1 - x)

Answer 3

Hmm your answer looks good, I think you just missed a negative sign in one spot.
