(\partial)/(\partial x)(cos(2x))

\frac{\partial}{\partial x} (cos (2 x))

- sin (2 x) \cdot 2

Solution steps

\frac{\partial}{\partial x} (cos (2 x))

Apply the chain rule:

- sin (2 x) \frac{\partial}{\partial x} (2 x)

= - sin (2 x) \frac{\partial}{\partial x} (2 x)

\frac{\partial}{\partial x} (2 x) = 2

= - sin (2 x) \cdot 2

\frac{d}{d x} (\frac{1}{x} + 1)

\int_{6}^{10} \frac{2}{x ^{3}} d x

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

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

\frac{d}{d x} (e^{- x l n (2 x)})
