derivative of

cos (π t)

- sin (π t) π

Solution steps

\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

= - sin (π t) π

\int_{1}^{3} - x^{2} + 4 x - 3 d x

\frac{d}{d x} (- e^{2 x})

\frac{d}{d x} (1 - \frac{x}{2} + \frac{x ^{2}}{9})

\frac{d}{d x} (ln (x e^{x} + 3))

\frac{d}{d x} (x^{3} (x^{4} - 1))
