What is the general notation when differentiating both sides of an equation with respect to x?

ddx(equation)=ddx(other side)\frac{d}{dx}(\text{equation}) = \frac{d}{dx}(\text{other side})dxd​(equation)=dxd​(other side)

What is the general notation when differentiating both sides of an equation with respect to x?

ddx(equation)=ddx(other side)\frac{d}{dx}(\text{equation}) = \frac{d}{dx}(\text{other side})dxd​(equation)=dxd​(other side)

What is the point-slope form of a tangent line equation?

y−y1=m(x−x1)y - y_1 = m(x - x_1)y−y1​=m(x−x1​), where mmm is the slope and (x1,y1)(x_1, y_1)(x1​,y1​) is a point on the line.

State the product rule.

ddx(uv)=udvdx+vdudx\frac{d}{dx}(uv) = u\frac{dv}{dx} + v\frac{du}{dx}dxd​(uv)=udxdv​+vdxdu​

How to find dydx\frac{dy}{dx}dxdy​ using implicit differentiation?

  1. Differentiate both sides with respect to xxx. 2. Apply chain rule to y terms. 3. Isolate dydx\frac{dy}{dx}dxdy​.

How to find the tangent line equation at a point?

  1. Find dydx\frac{dy}{dx}dxdy​ at the point. 2. Use point-slope form: y−y1=m(x−x1)y - y_1 = m(x - x_1)y−y1​=m(x−x1​).

What is implicit differentiation?

A method to find derivatives when yyy is not explicitly defined in terms of xxx.

What is dydx\frac{dy}{dx}dxdy​ in implicit differentiation?

Represents the derivative of yyy with respect to xxx, found when yyy is not explicitly defined.
