\frac{d}{d x} (- 3 tan (3 x))

- 9 sec^{2} (3 x)

Solution steps

\frac{d}{d x} (- 3 tan (3 x))

Take the constant out:

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

= - 3 \frac{d}{d x} (tan (3 x))

Apply the chain rule:

sec^{2} (3 x) \frac{d}{d x} (3 x)

= sec^{2} (3 x) \frac{d}{d x} (3 x)

\frac{d}{d x} (3 x) = 3

= - 3 sec^{2} (3 x) \cdot 3

Simplify

= - 9 sec^{2} (3 x)

\frac{d}{d x} (- a sin (x))

{\frac{( s + 2 ) ^{2}}{s ^{3}}}

x + 1 + x^{2}

\int (5 x^{9} - 11 x^{21}) d x

\int \frac{1}{x ^{3} - 512} d x
