\frac{d}{d x} (cos (2 x) - sin (x))

- sin (2 x) \cdot 2 - cos (x)

Solution steps

\frac{d}{d x} (cos (2 x) - sin (x))

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (cos (2 x)) - \frac{d}{d x} (sin (x))

\frac{d}{d x} (cos (2 x)) = - sin (2 x) \cdot 2

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

= - sin (2 x) \cdot 2 - cos (x)

\int_{1}^{16} \frac{x - 7}{x} d x

\int \frac{4}{( 1 + 2 x ) ^{3}} d x

\int_{1}^{e^{5}} \frac{ln ^{3} ( x ^{2} )}{x} d x

\int x^{- \frac{1}{4}} 1 + x^{\frac{1}{4}} d x

\frac{\partial}{\partial x} (5 x cos (x y))
