- Math (Calculus) (Implicit Differentiation) -
**Steve**, Sunday, May 12, 2013 at 3:32pm(x^2+y^2)^4=16x^2y^2

(x^2+y^2)^3 (x+yy') = 4xy^2 + 4x^2yy'

x(x^2+y^2)^3 + y(x^2+y^2)^3 y' = 4xy^2 + 4x^2yy'

(y(x^2+y^2)^3 - 4x^2y)y' = 4xy^2 - x(x^2+y^2)^3

y' = (4xy^2 - x(x^2+y^2)^3)/(y(x^2+y^2)^3 - 4x^2y)

at (1,-1) y' = (4-8)/(-8+4) = 1

So, now you have a point and a slope, so

y+1 = 1(x-1)
