#### Explanation:

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 **Horizontal.**

Since the **Normal** at

find that the reqd. normal is a **Vertical** line through P.

Therefore, the eqn. of the normal is
