What is the equation of the normal line of #f(x)= x^e/e^x # at #x=e#?
Thus, we require the eqn. of Normal to the Curve at the point
This means that, the Slope of Tangent at the point
the given curve is
In other words, the tgt. line at
Since the Normal at
find that the reqd. normal is a Vertical line through P.
Therefore, the eqn. of the normal is
