Question
5/6/7/8 AND 9 Y=
Find dy/dx by implicit differentiation. y cos x = 3x2 + 4y2 y' = If f(x) + x2[f(x)]4 = 18 and f(1) = 2, find f'(1). f'(1) = Need Help? Use implicit differentiation to find an equation of the tangent line to the curve at the given point. 7x2 + xy + 7y2 = 15, (1, 1) (ellipse) y - Need Help? Use implicit differentiation to find an equation of the tangent line to the curve at the given point. x2 + 2xy - y2 + x = 2, (1, 2) (hyperbola) y = Need Help? Use implicit differentiation to find an equation of the tangent line to the curve at the given point. x2 + y2 = (4x2 + 2y2 - x)2 (0, 0.5)(cardioid)
