The equation of the normal to the curve y= x drawn at the point nearest to the origin is
Options
- Ay=0
- Bx=1
- Cx=0
- Dy=1
Correct answer
C. x=0
Step-by-step solution
y= h x y^ = hx To find the nearest point to the origin, we can set the derivative equal to zero. h ( x )=0 The only solution of this equation is x=0 At x=0, y= cash (0)=1 The slope of normal is m = (- 1 y ^1 )_ (0,1) = (- 1 x )_ (0,1) m = -1 0 Now, the equation of the normal is (y-1)=- 1 0 (x-0) (x-0)=0 x=0
