## what is implicit differentiation?

Calculus uses implicit differentiation as a method to get a function's derivative when the definition of the function is implicit rather than explicit. In other words, implicit differentiation enables you to get the derivative of y with respect to x by treating y as an implicitly defined function when you have an equation that involves both x and y and it is difficult to isolate y as a function of x.

## how to do implicit differentiation works:

Start with the equation that relates x and y, for example F(x, y) = 0, where F is some function.

Differentiate both sides of the equation with respect to x.

You treat y as a function of x and apply the rules of differentiation, such as the product rule, chain rule, and power rule, when necessary.

After differentiating both sides, you will have an expression that involves derivatives like dy/dx (the derivative of y with respect to x) and dx/dx (which is 1).

If you're trying to find dy/dx, you can isolate it in the resulting equation to obtain the expression for the derivative.

Implicit differentiation is particularly useful when you have equations involving curves, circles, or other shapes that aren't easily expressed as y = f(x). It's a fundamental technique in calculus, especially in contexts where explicit solutions for y in terms of x are difficult to find.

## implicit differentiation formula:

Implicit differentiation is a technique used to find the derivative of a function when it's not possible or convenient to express one variable explicitly in terms of another. The formula for implicit differentiation involves applying the chain rule and product rule to differentiate both sides of the equation with respect to the independent variable.

Let's perform implicit differentiation on the equation $$F(x, y) = 0$$:

$\frac{{dF}}{{dx}} = \frac{{\partial F}}{{\partial x}} + \frac{{\partial F}}{{\partial y}} \cdot \frac{{dy}}{{dx}}$

Solving for $$\frac{{dy}}{{dx}}$$:

$\frac{{dy}}{{dx}} = -\frac{{\frac{{\partial F}}{{\partial x}}}}{{\frac{{\partial F}}{{\partial y}}}}$

## implicit differentiation example

Finding the Derivative of a Circle

Starting with the equation of the circle: $$x^2 + y^2 = r^2$$, where $$r$$ is the radius.

We differentiate both sides with respect to $$x$$:

\begin{align*} \frac{d}{dx}(x^2 + y^2) &= \frac{d}{dx}(r^2) \\ 2x + 2y\frac{dy}{dx} &= 0 \\ 2y\frac{dy}{dx} &= -2x \\ \frac{dy}{dx} &= \frac{-2x}{2y} \\ \frac{dy}{dx} &= \frac{-x}{y} \end{align*}

So, the derivative of $$y$$ with respect to $$x$$ for the circle is $$\frac{-x}{y}$$.

## Find dy/dx by implicit differentiation

We want to find $$\frac{dy}{dx}$$ for the equation $$x^2 + y^2 = 4$$.

Start by differentiating both sides with respect to $$x$$:

\begin{align*} \frac{d}{dx}(x^2 + y^2) &= \frac{d}{dx}(4) \\ 2x + 2y\frac{dy}{dx} &= 0 \end{align*}

Now, solve for $$\frac{dy}{dx}$$:

\begin{align*} 2y\frac{dy}{dx} &= -2x \\ \frac{dy}{dx} &= \frac{-2x}{2y} \\ \frac{dy}{dx} &= \frac{-x}{y} \end{align*}

So, the derivative $$\frac{dy}{dx}$$ for the equation $$x^2 + y^2 = 4$$ is $$\frac{-x}{y}$$.
