Hi Math help forum!
I'm finding it difficult to differentiation from first principals and wanted to know if there is a simple method I can follow. Could you please give an example aswell thanks.

That's what I wrote. Hence the $\displaystyle \Delta{x}\to{0}$. What seems to be the problem? These problems usually require some basic algebra manipulation. Try finding the derivatives of $\displaystyle f(x)=x^2$ and $\displaystyle f(x)=\frac{1}{x}$ using the limit definition. Or is there a specific one we can help you with?Originally Posted by dadon
