The normal at the point (1, 1) on the curve 2y + x 2 = 3 is

Question

Philoid · Accepted Answer

Given that the curve 2y + x² = 3 has a normal passing through point (1, 1).

Differentiating both the sides w.r.t. x,

Slope of the tangent

For (1, 1):

Equation of the normal:

⇒ y – 1 = x - 1

⇒ y - x = 0

⇒ x – y = 0

Hence, option B is correct.
