y^2 + 4xy +
x^2
= 13
f^2
(x) + 4x f(x) +
x^2
= 13
2f(x)
f′
(x)+4(f(x)+x
f′
(x))+2x=0
more easiliy written as
2y
y′
=4(y+x
y′
)+2x=0

Find the points on the lemniscate 2(x^2 + y^2)^2 = 25(x^2 - y^2) where the tangent is horizontal. The derivative using implicit differentiation is (-4x^3 - 4xy^2 + 25x)/(4x^3 + 4x^2 y + 25y)
