\frac{d}{d x} (cos (2 π x))

- sin (2 π x) \cdot 2 π

Solution steps

\frac{d}{d x} (cos (2 π x))

Apply the chain rule:

- sin (2 π x) \frac{d}{d x} (2 π x)

= - sin (2 π x) \frac{d}{d x} (2 π x)

\frac{d}{d x} (2 π x) = 2 π

= - sin (2 π x) \cdot 2 π

f (x) = 3 e^{2 x}

\int_{9}^{16} \frac{1}{9 - x} d x

\frac{d}{d x} (- \frac{11}{( x - 3 ) ^{2}})

x \to - 3 - lim (\frac{x ^{2}}{x + 3})
