\frac{d}{d x} (\frac{2}{( 1 + a \cdot e ^{b \cdot x^{2}} )})

- \frac{4 ab e ^{b x^{2}} x}{( 1 + a e ^{b x^{2}} ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{2}{( 1 + a e ^{b x^{2}} )})

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 2 \frac{d}{d x} (\frac{1}{1 + a e ^{b x^{2}}})

Apply exponent rule:

\frac{1}{a} = a^{- 1}

= 2 \frac{d}{d x} ((1 + a e^{b x^{2}})^{- 1})

Apply the chain rule:

- \frac{1}{( 1 + a e ^{b x^{2}} ) ^{2}} \frac{d}{d x} (1 + a e^{b x^{2}})

= - \frac{1}{( 1 + a e ^{b x^{2}} ) ^{2}} \frac{d}{d x} (1 + a e^{b x^{2}})

\frac{d}{d x} (1 + a e^{b x^{2}}) = 2 ab e^{b x^{2}} x

= 2 (- \frac{1}{( 1 + a e ^{b x^{2}} ) ^{2}} \cdot 2 ab e^{b x^{2}} x)

Simplify

2 (- \frac{1}{( 1 + a e ^{b x^{2}} ) ^{2}} \cdot 2 ab e^{b x^{2}} x) : - \frac{4 ab e ^{b x^{2}} x}{( 1 + a e ^{b x^{2}} ) ^{2}}

= - \frac{4 ab e ^{b x^{2}} x}{( 1 + a e ^{b x^{2}} ) ^{2}}

ln (4 - 2 cos (x))

\frac{1}{[ e ^{\frac{c}{x}} - 1 ]}

\frac{1}{( x + 2 )}

2 x - lo g_{10} (x) - 7

\frac{s}{( s ^{2} + 1 ) ^{2}}
