## anonymous 4 years ago x^2y-2x+3y=6 differentiation to find tangent on a line help plzz

1. dumbcow

so you are trying to solve for dy/dx or y' ??

2. anonymous

implicit

3. anonymous

trying to find the tangent of the line but u have find d/dx first

4. dumbcow

$\frac{dy}{dx} = \frac{2-2xy}{x^{2}+3}$

5. anonymous

y? i dnt understand hw u get that

6. dumbcow

by using implicit differentiation, you take derivative of each term but when you have a "y" the derivative is dy/dx $\rightarrow 2xy + x^{2}\frac{dy}{dx} -2 +3\frac{dy}{dx} = 0$ then isolate and solve for dy/dx

ohhhh
