dy/dx=(4x-2xy)/(x^2+y^2+1)

a) write an equation of each horizontal tangent line to the curve

b) the line through the origin with the slope .1 is tangent to the curve at P. Find x and y of point P.

- please help; calc -
**bobpursley**, Wednesday, November 12, 2008 at 8:05pmif dy/dx is zero, that must mean 4x-2xy is zero, or y=2

When y=2, solve for x in the original equation.

- please help; calc -
**stephanie**, Wednesday, November 12, 2008 at 10:11pmwhen you plug it in the original eqn. it doesn't work

- it doesn't work -
