    Find Tangent Line to Cardioid at (0, 0.5) Using Implicit Diff.

    Homework Statement Use implicit differentiation to find an equation of the tangent line to the cardioid at the point (0, 0.5). x2 + y2 = (2x2 + 2y2 - x)2Homework Equations Derivative rules point slope formula The Attempt at a Solution I got y' = [16x3-4x2+16xy2-4y2-4y2-8x2+2x] / [2y -...

    Implicit Derivative of y=31*arctan(x)

    Homework Statement Find the derivative of the following function. Simplify where possible. y=31*arctan(sqrt(x)) Homework Equations I know that the derivative of arctan(x) = 1 / (1+x2) I also know we will be using chain rule and product rule. The Attempt at a Solution y' =...
