\frac{d}{d x} (2^{c o s (x)})

- ln (2) \cdot 2^{c o s (x)} sin (x)

Solution steps

\frac{d}{d x} (2^{c o s (x)})

Apply exponent rule:

a^{b} = e^{b l n (a)}

2^{c o s (x)} = e^{c o s (x) l n (2)}

= \frac{d}{d x} (e^{c o s (x) l n (2)})

Apply the chain rule:

e^{c o s (x) l n (2)} \frac{d}{d x} (cos (x) ln (2))

= e^{c o s (x) l n (2)} \frac{d}{d x} (cos (x) ln (2))

\frac{d}{d x} (cos (x) ln (2)) = - ln (2) sin (x)

= e^{c o s (x) l n (2)} (- ln (2) sin (x))

Simplify

e^{c o s (x) l n (2)} (- ln (2) sin (x)) : - ln (2) \cdot 2^{c o s (x)} sin (x)

= - ln (2) \cdot 2^{c o s (x)} sin (x)

n = 0 \sum \infty 2^{3 - 2 n}

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

\frac{\partial}{\partial t} (2 s^{2} t^{2})

\int x^{2} 8 + x d x

\frac{d}{d x} (arccot (\frac{1}{2}) (x - \frac{1}{x}))
