\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

t^{6} e^{8 t}

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

x \to 3 + lim (8 - x)

f (x) = tan (π x)
