What is the difference between derivative and differential ? Please Help !
The derivative of a function of a real variable measures the sensitivity to change of a quantity which is determined by another quantity (the independent variable). In calculus, the differential represents a change in the linearization of a function. The notion of a differential motivates several concepts in differential geometry (and differential topology). Differentials are also important in algebraic geometry, and there are several important notions.
medal please?

There you go :) I still am not clear about it , could you explain in simpler terms
I am reading your answer but not able to imagine it :(
In short : derivative measures "rate of change" differential measures "change"
\[\begin{align} y(x) &= x^2&&\text{(equation)}\\~\\ \mathrm dy &= 2x\,\mathrm dx&&\text{(differentials)}\\~\\ \frac{\mathrm dy}{\mathrm dx}&= 2x&&\text{(derivative)} \end{align}\]
@Dexter810: this link will help you I guess

Thanks a ton ! :)
