derivative of

cos (x) - 4 tan (x)

- sin (x) - 4 sec^{2} (x)

Solution steps

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

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

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

\frac{d}{d x} (cos (x)) = - sin (x)

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

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

\frac{\partial}{\partial x} (8 - x^{2} - 3 y^{2})

(2 x^{3} + 4) (x^{4} - 4 x)

\frac{6}{x ^{3}} - \frac{6}{x ^{2}} - \frac{1}{x} + 350

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

\frac{d}{d x} (2 x + 2 x ln (x))
