(\partial)/(\partial x)(1/(x-b))

\frac{\partial}{\partial x} (\frac{1}{x - b})

- \frac{1}{( x - b ) ^{2}}

Solution steps

\frac{\partial}{\partial x} (\frac{1}{x - b})

Treat

b

as a constant

Apply exponent rule:

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

= \frac{\partial}{\partial x} ((x - b)^{- 1})

Apply the chain rule:

- \frac{1}{( x - b ) ^{2}} \frac{\partial}{\partial x} (x - b)

= - \frac{1}{( x - b ) ^{2}} \frac{\partial}{\partial x} (x - b)

\frac{\partial}{\partial x} (x - b) = 1

= - \frac{1}{( x - b ) ^{2}} \cdot 1

Simplify

= - \frac{1}{( x - b ) ^{2}}
