1.	if the curves f[x, y]=0 Q[x ,y]=0 touch each other .show that at the point of contact df /dx [dQ/dy] - df/dy [dQ/dx]
Answer» Answer: When f = f (x, y) and U = u(x, y) is FOUND such that f = f (u). ∂f ... Taking y to be fixed: DY = 0 Taking x to be fixed: dx = 0 df du. = ∂f. ∂x dx ... Show that, no matter what f is EXACTLY, z satisfies.
