x2y2 + (y+1)e-x=2 + x
Defines y as a differentiable function of x at point (x, y) = (0,1)
Find y′:
My attempt:
∂y/∂x =2xy3 + (-y-1)e-x=1
∂y/∂y = 3x2y2 - e-x=0
Plugging in for x and y ⇒
∂y/∂x = -3
∂y/∂x = -1
For some reason I think y′ is defined as
(∂y/∂x) /(∂y/∂y) = 3
At leas this give the right answer (from solutions), but I am uncertain so I hope someone can correct me where I am wrong.
