\frac{d}{d x} (cos^{2} (2 x + 1))

- 4 cos (2 x + 1) sin (2 x + 1)

Solution steps

\frac{d}{d x} (cos^{2} (2 x + 1))

Apply the chain rule:

2 cos (2 x + 1) \frac{d}{d x} (cos (2 x + 1))

= 2 cos (2 x + 1) \frac{d}{d x} (cos (2 x + 1))

\frac{d}{d x} (cos (2 x + 1)) = - sin (2 x + 1) \cdot 2

= 2 cos (2 x + 1) (- sin (2 x + 1) \cdot 2)

Simplify

= - 4 cos (2 x + 1) sin (2 x + 1)

\int \frac{3}{5} d x

\frac{\partial}{\partial x} (x^{2} + y^{2} + z^{2} - 2 yz)

\frac{d}{d x} (d y (d, x))

\frac{7}{x}, 4

\int_{1}^{4} x ln (\frac{x}{2}) d x
