normal is parallel to x axis means dy/dx = 0
 
Dear student
 
hence dx/dy = infinity
 
Hope it helps
 
Thanks and regards

dear student your language of ques is not at all clear and hard to understand.
however, if at some point on the curve the normal is given to be parallel to x axis, then certainly dx/dy= 0 at that point.
