okay let's do some math Oh fun this question is actually on the topper of a high school math book in Hungary as you guys can see from the screenshot right here so I think it's really cool and I really appreciate this kind of scenes that when they put a really nice question on the cover of a math book except Apple oranges so I really like this anywa...

Questions & Answers
Q: What is implicit differentiation?
Implicit differentiation is a method used to find the derivative of a function that cannot be easily solved for y. It involves differentiating both sides of an equation with respect to x.
Q: Why is the natural log applied to both sides of the equation?
Applying the natural log to both sides allows the power to be brought to the front, making it easier to differentiate. The derivative of ln(y) is 1/y, which simplifies the equation.
Q: How is the product rule applied in implicit differentiation?
The product rule is used when there is a product of two functions. In this case, the first function is x and the second function is ln(sine(xy)). The derivative of ln(sine(xy)) is (1/sin(xy)) * (cos(xy)) * (x + y).
Q: Why is the chain rule used multiple times in the differentiation process?
The chain rule is used to differentiate composite functions. In this case, the chain rule is used with functions such as sine(xy) and xy. Each time the chain rule is applied, the derivative of the inner function is multiplied by the derivative of the outer function.
