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

- sin (3 x^{2} + 1) \cdot 6 x

Solution steps

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

Apply the chain rule:

- sin (3 x^{2} + 1) \frac{d}{d x} (3 x^{2} + 1)

= - sin (3 x^{2} + 1) \frac{d}{d x} (3 x^{2} + 1)

\frac{d}{d x} (3 x^{2} + 1) = 6 x

= - sin (3 x^{2} + 1) \cdot 6 x

\int_{0}^{\infty} \frac{1}{x ^{2} + 1} d x

\frac{d y}{d x} = 29 - y

(1 + 4 x)^{\frac{3}{2}}, at x = 2

\int \frac{e ^{x}}{25 - e ^{2 x}} d x

x \to + (- 1) lim (\frac{k x + 3}{4})
