Use implicit differentiation to find an equation of the tangent line to the curve at the given point. The curve is represented by the equation y²(y² - 4) = x²(x² - 6) and the point is (0, -2) (devil's curve).

Final answer:

To find the equation of the tangent line to the curve at the given point, we can use implicit differentiation and the point-slope form of a line.

Step-by-step explanation:

To find the equation of the tangent line to the curve at the point (0, -2), we can use implicit differentiation. Let's start by differentiating both sides of the equation y²(y² - 4) = x²(x² - 6) with respect to x.

On the left-hand side, we can apply the product rule and chain rule, which gives 2yy'(y² - 4) + y²(2yy') = 2x(x² - 6) + x²(2x).

Next, we substitute the coordinates of the given point, (0, -2), into the equation and solve for y'. Plugging in x = 0 and y = -2, we have -8y' + 4 = 0, which gives y' = 1/2.

Therefore, the equation of the tangent line to the curve at the point (0, -2) is y = (1/2)x - 2.
