24yaa.......i too cant understand the ques.......plz clear it.
for any differentiable function y=f(x)
d2y/dx2 + (dy/dx)3(d2x/dy2) = ???????
kaise approach kare plz batayie

21??????? kya hai.... like do v hav 2 find it or wat?
is it a differential equatin
21i think here we have to find d2x/dy2 in terms of dy/dx and d2y/dx2. is the answer 0??????
21soln - dx/dy= 1/(dy/dx)
diff. both sides wrt y->
d2x/dy2= (-d2y/dx2)/(dy/dx)3 [using qoutient rule]
now just put the value in the above equation .............
