Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

If the tangent is parallel to the y-axis then

$\displaystyle \sf{ \frac{dx}{dy} } =$

(1) 0

(2) infinity

(3) 1

(4) 2

EVALUATION

Here it is given that the tangent is parallel to the y-axis

Let the equation of the tangent is

x = constant

Differentiating both sides with respect to y we get

$\displaystyle \sf{ \frac{dx}{dy} = 0}$

FINAL ANSWER

Hence the correct option is (1) 0
