Find the equation

Answer :

finding slope of the tangent by differentiating the curve




m(tangent) at (x1, y1) =


normal is perpendicular to tangent so, m1m2 = – 1


m(normal) at (x1, y1) =


equation of tangent is given by y – y1 = m(tangent)(x – x1)



equation of normal is given by y – y1 = m(normal)(x – x1)
