find all points on the curve x^2y^2+xy=2 where the slope of the tangent line is 1
I know that you have to find the derivative when it equals 1
i got
y'=(2x*y^2y)/(2x^2*y+x)
(i don't know if it is correct or not)
but i don't know how to go from here. any help would be good
Thanks

Find the equation of the line tangent to the curve at (5, 3) (x2)^2 + (y+3)^2 = 9 I solved the derivative to be dy/dx = ((2x+4)/ (2y+6)) when i plugged in the points (5, 3) I got the slope as 6/0...How is this possible?

Find all points on the curve x^2y^2+xy=2 where the slope of tangent line is 1. This is what I got. x^2y^2+xy=2 x^2*2ydy/dx + 2x*y^2 + x*dy/dx + y =0 dy/dx(2yx^2+x)= 2xy^2y dy/dx = (2xy^2y)/(x+2yx^2) how do I finish from here?
