\frac{d}{d x} (cos (π \cdot x))

- sin (π x) π

Solution steps

\frac{d}{d x} (cos (π x))

Apply the chain rule:

- sin (π x) \frac{d}{d x} (π x)

= - sin (π x) \frac{d}{d x} (π x)

\frac{d}{d x} (π x) = π

= - sin (π x) π

x^{2} \cdot e^{x} + 4 \cdot y \cdot e^{(- y)} \cdot y^{^{'}} = 0

\frac{d}{d x} ((x - 1) ln (x - 1))

\int_{0}^{x^{2}} t^{2} d t

y = 5 x^{4} - x^{2} + 6

\frac{d}{d x} (2 x + 9)
