The normal to the curve x² = 4y passing through (1, 2) is

Given that the curve x² = 4y

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

Slope of the tangent

For (1, 2):

Equation of the normal:

⇒ y – 2 = -2x + 2

⇒ y + 2x = 4

No option matches the answer.

The line y = mx + 1 is a tangent to the curve y² = 4x, if the value of m is

The normal at the point (1, 1) on the curve 2y + x² = 3 is

Find the point on the curve y = x² – 2x + 3, where the tangent is parallel to x-axis.

Find the slope of the tangent to the curve x = t² + 3t – 8, y = 2t² – 2t – 5 at t = 2.
