The equation of normal to the curve y = l o g e x at the point P 1 , 0 is ________
Options
- A2 x + y = 2
- Bx - 2 y = 1
- Cx - y = 1
- Dx + y = 1
Correct answer
D. x + y = 1
Step-by-step solution
Given curve is y = log e x and point p 1 , 0 then, d y d x = 1 x Hence, equation of normal is y = - 1 x - 1 ⇒ x + y = - 1 ¯
