MHT CET 2026 Mathematics question
The tangent to the curve intersects the Y-axis at point P. A line drawn through point P is perpendicular to this tangent and passes through another point (1, 0). The differential equation of the curve is…
Answer: (A)
Solution
Let the tangent at have slope . Its equation is ; at , , so . The line through P perpendicular to the tangent also passes through , so its slope is . Perpendicularity:
