Do you know how to differentiate an expression with one variable?
So, you can express the derivative of what you got as:
You can differentiate the first part?
For the second part, let me give you an example.
As you can see, you differentiate the y similar to how you differentiate x, but you just add dy/dx after differentiating.
For the middle part of your problem, use the product rule.
If I may. Allow me to show a method I often use for implicit diff.
Use
i.e.
Just a thought if anyone is interested.
I wasn't sure what you did at first, but when I expanded it, I understood. Interesting method :)
You only missed a 'y' in the denominator ;)
