derivative of

cos (2 x + 1)

- sin (2 x + 1) \cdot 2

Solution steps

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

Apply the chain rule:

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

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

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

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

y = \frac{1 + 2 x}{3 - 4 x}

x \to 0 + lim (\frac{e ^{x}}{1 - e ^{x}})

\int cot (2 x) d x

\int \frac{10}{2 x + 3} d x

\frac{\partial}{\partial x} (x^{4} + y^{4} - 4 x y + 1)
