Problem Statement: ECE Board April 1999
Find the equation of the normal to x^2+y^2=5 at the point (2, 1).
- A. y = 2x
- B. x = 2y
- C. 2x + 3y = 3
- D. x + y = 1
Note: The slope of the line normal to the curve at the given point is equal to the negative of the reciprocal of the slope of the given curve.
The equation of the normal is equal to x = 2y
