Implicit Differentiation: Solving for dy/dx in (x^2-y^2)^2=(x+y)^3

In summary, implicit differentiation is a mathematical technique used to find the derivative of a function that is defined implicitly. It is used when it is difficult to solve for y in terms of x and when the function is defined implicitly. It differs from explicit differentiation in that it involves finding the derivative of a function that is defined implicitly. The process of implicit differentiation involves differentiating both sides of an equation and solving for the derivative of the dependent variable. Some common applications of implicit differentiation include physics, engineering, economics, and finance.

(x^2-y^2)^2=(x+y)^3
I tried to use the chain rule on both sides but it didn't work because y needs to have the chain rule used on it explicitly and if i differentiate y explicitly then use the chain rule on everything i would be finding the 2nd derivative. So how do i differentiate this?

For starters, what is the derivative with respect to x of [itex](x^2-y^2)^2[/itex]? Of [itex](x+y)^3[/itex]?

What does the question ask of you? That you find dy/dx as a function of x only, or simply to implicitly differentiate it?
 

What is implicit differentiation?

Implicit differentiation is a mathematical technique used to find the derivative of a function that is defined implicitly, meaning it is not explicitly written in the form of y = f(x). This allows us to find the rate of change of a function with respect to its independent variable.

When is implicit differentiation used?

Implicit differentiation is used when it is difficult or impossible to solve a function for y in terms of x. It is also used when the function is defined implicitly, such as in equations involving multiple variables or in polar coordinates.

How is implicit differentiation different from explicit differentiation?

Explicit differentiation involves finding the derivative of a function that is written explicitly in the form of y = f(x). Implicit differentiation, on the other hand, involves finding the derivative of a function that is defined implicitly and cannot be easily written as y = f(x).

What is the process of implicit differentiation?

The process of implicit differentiation involves differentiating both sides of an equation with respect to the independent variable, treating the dependent variable as a function of the independent variable. Then, the derivative of the dependent variable is solved for to find the rate of change of the function.

What are some common applications of implicit differentiation?

Implicit differentiation is commonly used in physics and engineering to find rates of change in dynamic systems. It is also used in economics and finance to analyze supply and demand curves and optimize production processes.
