    IMolicit differentiation

    one more im not sure about

    e^(x+y) +x-y^2=3

    sorry about the confusion
    it is e^(x+y)+x-y^2=3

    e^x+y'-2y\cdot{y'}=0

    I assume

    err.. herm..

    \frac{d}{dx}\left( e^x+y+x-y^2\right)=e^x+\frac{dy}{dx}+1-2y\frac{dy}{dx}

    I would say e^{x+y}+(x-y)^2

    Te derivative is \underbrace{(1+y')e^{x+y}}_{\text{chain rule}}+\underbrace{2(1-y')(x-y)}_{\text{chain rule}}

    Please use brackets to make the expression unambiguous. The normal precedence of operators means that without brackets this represents:

    e^x + y + x + y^2

    if you intend anything else you need to use brackets.

    But you are only guessing the OPs intention, that is not what they wrote?!

    Isn't "would" a sign of "condition" ? lol

    It doesn't matter actually ^^

    See ya
