(\partial)/(\partial x)(cos(3x))

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

- sin (3 x) \cdot 3

Solution steps

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

Apply the chain rule:

- sin (3 x) \frac{\partial}{\partial x} (3 x)

= - sin (3 x) \frac{\partial}{\partial x} (3 x)

\frac{\partial}{\partial x} (3 x) = 3

= - sin (3 x) \cdot 3

\int (sec (x) - \frac{1}{sin ( x )} + cos (x)) d x

\frac{\partial}{\partial x} (sin (\frac{x}{1 + y}))

\int 27 sec^{- 2} (x t a) n^{3} x d x

\frac{d y}{d x} = y (c_{1} + π^{2}) (1 + x)^{- 1}
