Hi!

Problem:

Find dz/dx when z(y, dy/dx) is given as follows

z = (dy/dx)

My attempt:

z = dy/dx

dz/dx = d^{2}y/dx^{2}

Question:

I do not know how to interpret the information regarding the function z, that z is given as z(y, dy/dx)?

Im hoping somone could help me by explaining how to go about this problem? Also the whole differentiation of a differentiation thing... hard to phrase myself correcly

Also how would I solve the differentiation if:

z = (y*dy/dx), here introducing the variable y aswell.

Thank you!

PS: I dont want a solved answer, preferably want some guidance and explanations!
