I think the point of the exercise is that it's OK to have the second derivative in terms of and . Note. When you have y' in your answer use the first part to eliminate it.
Hi everyone i can't solve this problem:
Find if
I used implicit differentiation an found that DY/DX = -5x/3y
(The second derivative can't be expressed solely using .)
So for i know i have to use the quotient rule but the answer will have y.
Thank you
thank you but i still don't understand.
I brought down the first derivative and i got:
(-5/3)*[y-x*(-5/3)(x/y)]/(y^2)
But now i don't know how to continue and simplify this. If you could explain it to me
Thanks
