A) \[\frac{dy}{dx}=0\]
B) \[\frac{dy}{dx}=1\]
C) \[\frac{dx}{dy}=0\]
D) None of these
Correct Answer: C
Solution :
Slope of the normal = \[-\frac{1}{\left( \frac{dy}{dx} \right)}\] This is parallel to x-axis Þ \[-\frac{1}{\left( \frac{dy}{dx} \right)}=0\]Þ \[\frac{dx}{dy}=0\].You need to login to perform this action.
