Question

# Find derivatives of the functions defined as follows. y=\frac{e^{x}}{2x+1}

Derivatives
$$\displaystyle{y}={\frac{{{e}^{{{x}}}}}{{{2}{x}+{1}}}}$$
$$\displaystyle{\frac{{{\left.{d}{y}\right.}}}{{{\left.{d}{x}\right.}}}}={\frac{{{\left({2}{x}-{1}\right)}{e}^{{{x}}}}}{{{\left({2}{x}+{1}\right)}^{{{2}}}}}}$$
