## anonymous 5 years ago does anyone know how to find the derivative of e^2x/1+x?

1. anonymous

do you have a graphing calculator? if so, you can do it on there

2. anonymous

no i do not, my teacher wont let us use one

3. anonymous

T_T no i cant figure it out, sorry!

4. anonymous

its okay

Use the quotient rule: $\frac{d}{dx} (\frac{f(x)}{g(x)}) = \frac{g(x)*f'(x) - f(x)*g'(x)}{g(x)^{2}}$

Since you're given d/dx ($\frac{e^{2x}}{1+x}$ $f(x) = e^{2x} \ \ f'(x) = 2e^{2x} \ \ g(x) = 1+x \ \ g'(x) = 1$ Plug in and solve!
