How Do You Isolate dy/dx in Implicit Differentiation?

Click For Summary
To isolate dy/dx after implicitly differentiating the equation x/y + y/x = 2y, the key is to differentiate each term correctly while applying the product and quotient rules. After differentiating, the resulting equation will typically involve dy/dx on both sides. To isolate dy/dx, rearranging the equation to group all terms involving dy/dx on one side and constant terms on the other side is essential. Simplifying the equation will help in isolating dy/dx effectively. This process allows for a clearer understanding of the relationship between x and y in implicit differentiation.

Homework Statement



Calculate the derivative with respect to x:
x/y + y/x = 2y

Homework Equations



n/a

The Attempt at a Solution



I end up getting the right answer, but what I want to know is how to isolate dy/dx to one side after implicitly differentiating. I have tried differentiating the LHS sum by its terms, and also tried getting the common denominator first of the LHS and differentiating that, but I can't isolate dy/dx.

(I understand that I could isolate y instead and take the derivative, but I wanted to know if there was a way to isolate dy/dx to one side after implicitly differentiating).

What is your result upon implicitly differentiating?

It shouldn't be all that difficult to isolate dy/dx .
 
Question: A clock's minute hand has length 4 and its hour hand has length 3. What is the distance between the tips at the moment when it is increasing most rapidly?(Putnam Exam Question) Answer: Making assumption that both the hands moves at constant angular velocities, the answer is ## \sqrt{7} .## But don't you think this assumption is somewhat doubtful and wrong?
