derivative of

cos (3 x^{2})

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

Solution steps

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

Apply the chain rule:

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

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

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

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

\frac{d y}{d x} = - 9 y, y (0) = - 5

\frac{8 + 5 x}{x ^{2} + 9}

\int_{0}^{\frac{π}{2}} 9 cos^{5} (x) d x

\int e^{2 x} x + \frac{3}{2} e^{2 x} d x

n = 1 \sum \infty \frac{3 n}{5 n + 1}
