\frac{d}{d x} (ln (x - 8))

\frac{1}{x - 8}

Solution steps

\frac{d}{d x} (ln (x - 8))

Apply the chain rule:

\frac{1}{x - 8} \frac{d}{d x} (x - 8)

= \frac{1}{x - 8} \frac{d}{d x} (x - 8)

\frac{d}{d x} (x - 8) = 1

= \frac{1}{x - 8} \cdot 1

Simplify

= \frac{1}{x - 8}

\int \frac{cos ( x )}{sin ^{2} ( x ) - 9} d x

\int \frac{x}{1 + x ^{\frac{3}{2}}} d x

\frac{\partial}{\partial x} (cos (x^{2} + y^{2} - z))

\frac{d}{d x} (B e^{x})

\int - y^{2} e^{y} d y
