derivative of

5 cos (π t)

- 5 π sin (π t)

Solution steps

\frac{d}{d t} (5 cos (π t))

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 5 \frac{d}{d t} (cos (π t))

Apply the chain rule:

- sin (π t) \frac{d}{d t} (π t)

= - sin (π t) \frac{d}{d t} (π t)

\frac{d}{d t} (π t) = π

= 5 (- sin (π t) π)

Simplify

= - 5 π sin (π t)

\int_{0}^{3} (x + 1) (2 x - 3) d x

\frac{\partial}{\partial x} (4 x^{3} y^{3} + 3)

\frac{d}{d n} (2^{n})

\frac{x - 1}{x + 1}

x y^{^{'}} = y + x^{2} sin (x), y (π) = 0
