NettetComplete the equation of the line tangent to the graph of f (x)=x^2 f (x) = x2 at x=3 x = 3. y= y = And we're done! Using the definition of the derivative, we were able to find the equation for the line tangent to the graph of f (x)=x^2 f (x) = x2 at x=3 x = 3. Nettet28. des. 2024 · The normal line has the opposite--reciprocal slope as the tangent line, so its equation is y ≈ 1 3.83x + 1.26. To find the horizontal lines of tangency, we find where dy dx = 0; thus we find where the numerator of our equation for dy dx is 0. cosθ(4sinθ + 1) = 0 ⇒ cosθ = 0 or 4sinθ + 1 = 0. On [0, 2π], cosθ = 0 when θ = π / 2, 3π / 2.
