Find equation of tangent line at given point implicit differentiation

When x is 1, y is 4. So we want to figure out the slope of the tangent line right over there. So let's start doing some implicit differentiation. So we're going to take the derivative of both sides of this relationship, or this equation, depending on how you want to view it. And so let's skip down here past the orange. Use implicit differentiation to find an equation of the tangent line to the curve at the given point.? x2 + 2xy − y2 + x = 39, (5, 9)One method to find the slope is to take the derivative of both sides of the equation with respect to x. When taking the derivative of an expression that contains y, you must treat y as a function of x. This method is called implicit differentiation and it is illustrated below.

On the other hand, if we want the slope of the tangent line at the point , we could use the derivative of . However, it is not always easy to solve for a function defined implicitly by an equation. We've been doing a lot of examples where we just take implicit derivatives, but we haven't been calculating the actual slope of the tangent line at a given point. And that's what I want to do in this video. So what I want to do is figure out the slope at x is equal to 1. So when x is equal to 1.Implicit Differentiation. Finding the derivative when you can’t solve for y . You may like to read Introduction to Derivatives and Derivative Rules first. Implicit vs Explicit.
