## TL;DR

This video covers the process of taking derivatives using implicit differentiation and demonstrates step-by-step how to solve a specific problem.

## Key Insights

• ❓ Implicit differentiation is used when solving for the derivative of an equation with multiple variables that cannot be easily solved explicitly.
• 📏 The process involves differentiating each term of the equation separately using rules like the chain rule and the product rule.
• 👻 Implicit differentiation allows for finding derivatives even when it is not possible to solve for one variable in terms of the other.

3.5 number 17 we are going to take the derivative of this function our tangent or the inverse tangent of x squared times y inside is equal to x plus x times y squared so this requires implicit differentiation we'll just put d dx all the way in front put parenthesis that will represent we're taking the derivative and now that's just going to work th...

### Q: What is implicit differentiation?

Implicit differentiation is a technique used to find derivatives of equations where it is not possible to solve explicitly for one variable in terms of the other.

### Q: How is chain rule used in implicit differentiation?

In implicit differentiation, when taking the derivative of a function involving multiple variables, the chain rule is used to differentiate each term separately.

### Q: What is the product rule in implicit differentiation?

The product rule states that the derivative of a product of two functions is the first function times the derivative of the second function, plus the second function times the derivative of the first function.

### Q: Can implicit differentiation be used for any type of equation?

Implicit differentiation is particularly useful for equations that cannot be easily solved for one variable explicitly, such as when the equation involves trigonometric or inverse functions.
