# Find the equation

given: ay2 = x3 is the curve, and the point is am2 at which normal is required

Differentiating the curve to get the slope of the tangent

Formula: mtangentmnormal = - 1

Finding the corresponding y coordinate for the given x coordinate

ay2 = a3m6

y2 = a2m6

y = am3 or - am3

therefore

Now, we know that,

Equation of line: (y – y1) = mnormal(x – x1)

the equation of normal is

or
