nexis Group Title Use the definition of the derivative to compute: d/dx x/(x+1) one year ago one year ago

1. nexis Group Title

$(\frac{ x+h }{ x+h+1 }-\frac{x}{x+h})*1/h$ I've plugged it into the equation, but can't seem to get anywhere with the algebra part

2. hartnn Group Title

because its x+1 in 2nd term

3. hartnn Group Title

the algebra part is very easy (x+h)(x+1) - x(x+h+1) simply turns out to be h

ahh wow

5. nexis Group Title

that was actually it

6. nexis Group Title

think I need to figure out a way to focus better
