\frac{d}{d x} (cos (tan (7 x)))

- sin (tan (7 x)) sec^{2} (7 x) \cdot 7

Solution steps

\frac{d}{d x} (cos (tan (7 x)))

Apply the chain rule:

- sin (tan (7 x)) \frac{d}{d x} (tan (7 x))

= - sin (tan (7 x)) \frac{d}{d x} (tan (7 x))

\frac{d}{d x} (tan (7 x)) = sec^{2} (7 x) \cdot 7

= - sin (tan (7 x)) sec^{2} (7 x) \cdot 7

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

tan (x) - sin (x)

\frac{\partial}{\partial x} (ln (x + 8 y + 7 z))

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

\int (\frac{7}{x} - \frac{3}{x ^{2}}) d x
