The normal to the curve x=a(1+ ) , y=a at always passes through a fixed point, then the fixed point is
Options
- A(a, 0)
- B(0, a)
- C(0,0)
- D(a, a)
Correct answer
A. (a, 0)
Step-by-step solution
Given, x=a(1+ ) aligned & and y=a & d x d =a(- ) & d y d =a d x d y =- & -d x d y = , [ Slope of normal = -1 d y / d x ] & aligned Slope of normal = Equation of normal is aligned & y-a = (x-a-a ) & y-a =x -a -a & y= (x-a) aligned The line passes through the point (a, 0) .
