Derive the implicit function of the three high numbers in postgraduate mathematics after class. I first find the derivative of x, and then find the derivative of y in the original formula. The answer is another way. Is my method wrong? 1, your method is not given.

2. Take the derivative of the implicit function of the three high numbers in the postgraduate mathematics after class. I first find the derivative of x, and then find the derivative of y to the original formula. The answer is another way.

What you said is also right.

Derivation of implicit function, the final result can have both independent variables and implicit variables. The surface form of the result can be different.
