    Does anyone else think people often have misconceptions about differentiating and using wrong notation/not fully understanding it. Are schools to blame?
    Like you see  \frac{dy}{dx} (x)=1 .

    ...your point is?
    If there is no equal sign then what is it.
    Its impossible k.

    Incredibly so. Another common thing in students books that I hate seeing is stuff like this:

    \displaystyle

\begin{align*}y = x^2 + 2x + \frac{3}{x} & = x^2 + 2x^1 + 3x^{-1} \\ & = 2x + 2 - 3x^{-2} \\ & = 2x + 2 - \frac{3}{x^2} = \frac{\mathrm{d}y}{\mathrm{d}x} \end{align*}

    My answer is as follows:

    [cos(a)*(dy/dx)*a-sin(a)*y*a]*[y*a+(dy/dx)*x*a]

    Where a=e^xy

    By my calculus is rusty so....

    P.S. I have no idea how you managed to put proper fractions and stuff in your answer because I don't use this site very much

    Why do you assume there must be an equals sign?
    The definition of an equation is
    "a statement that the values of two mathematical expressions are equal (indicated by the sign =)."

    I'm well aware of what an equation is. Why is this 'a must' for differentiating, exactly?

    i was just going off the fact that there is no equal sign :hoppy:
    a = cos(e^xy)*y(e^xy)

    Find da/dx.

    Happy now?

    Well... that's worrying.

    Well hey, it would be alright if y=e^x....... ;D
