Hi! I'm new to those forums, so I just want to say "Hello everbody!". To my question: How can I simplify [tex]\frac{\frac{1}{x+\Delta x}-\frac{1}{x}+ \frac{1}{x^2}\Delta x}{\Delta x}[/tex] I've spent some hours on google, but no result. Just tell me the name of the method and I'm really gratefull!(adsbygoogle = window.adsbygoogle || []).push({});
