derivative of

sec (9 x)

sec (9 x) tan (9 x) \cdot 9

Solution steps

\frac{d}{d x} (sec (9 x))

Apply the chain rule:

sec (9 x) tan (9 x) \frac{d}{d x} (9 x)

= sec (9 x) tan (9 x) \frac{d}{d x} (9 x)

\frac{d}{d x} (9 x) = 9

= sec (9 x) tan (9 x) \cdot 9

\frac{d}{d x} (4.5 x + 2.4 x^{2} + 1.1 x^{3})

\frac{d}{d x} (ln (x y))

\frac{d}{d w} ((ln (w))^{(2 w)})

\int_{0}^{π} 4 \cdot sin (x) d x

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