derivative of

f (x) = 2 - x

- \frac{1}{2 x}

Solution steps

\frac{d}{d x} (2 - x)

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{d}{d x} (2) - \frac{d}{d x} (x)

\frac{d}{d x} (2) = 0

\frac{d}{d x} (x) = \frac{1}{2 x}

= 0 - \frac{1}{2 x}

Simplify

= - \frac{1}{2 x}

\int \frac{( x + 1 )}{x ^{2} ( x - 1 )} d x

\int_{300}^{360} \frac{2400}{x ^{2}} d x

x \frac{d y}{d x} + y = y^{- 2}

\int \frac{1}{( 4 t ^{2} + 9 ) ^{2}} d t

\int_{- \infty}^{0} x e^{(3 x)} d x
