derivative of

y = cos ((π x)^{8})

- sin (π^{8} x^{8}) \cdot 8 π^{8} x^{7}

Solution steps

\frac{d}{d x} (cos ((π x)^{8}))

Simplify

cos ((π x)^{8}) : cos (π^{8} x^{8})

= \frac{d}{d x} (cos (π^{8} x^{8}))

Apply the chain rule:

- sin (π^{8} x^{8}) \frac{d}{d x} (π^{8} x^{8})

= - sin (π^{8} x^{8}) \frac{d}{d x} (π^{8} x^{8})

\frac{d}{d x} (π^{8} x^{8}) = 8 π^{8} x^{7}

= - sin (π^{8} x^{8}) \cdot 8 π^{8} x^{7}

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

\frac{d y}{d x} = 100 x (y + 2)

y = 3 e^{x} cos (x), (0, 3)

4 y^{^{''}} + 12 y^{^{'}} + 9 y = 0

y^{^{'}} = \frac{y}{x} + 2 x + 1
