\frac{d}{d x} (cos (tan (4 x)))

- sin (tan (4 x)) sec^{2} (4 x) \cdot 4

Solution steps

\frac{d}{d x} (cos (tan (4 x)))

Apply the chain rule:

- sin (tan (4 x)) \frac{d}{d x} (tan (4 x))

= - sin (tan (4 x)) \frac{d}{d x} (tan (4 x))

\frac{d}{d x} (tan (4 x)) = sec^{2} (4 x) \cdot 4

= - sin (tan (4 x)) sec^{2} (4 x) \cdot 4

\frac{d}{d x} (\frac{x ^{3} - 6 x ^{2} + 5}{x})

n = 0 \sum \infty (\frac{1}{6})^{n}

\frac{\partial}{\partial y} (e^{x y})

\frac{\partial}{\partial y} (3 cos (y))

x \to 3 lim (\frac{( x ^{4} - 81 )}{x - 3})
