2^{x} ln (2) sec (x) + sec (x) tan (x) \cdot 2^{x}

Schritte zur Lösung

\frac{d}{d x} (\frac{2 ^{x}}{cos ( x )})

Vereinfache

\frac{2 ^{x}}{cos ( x )} : 2^{x} sec (x)

= \frac{d}{d x} (2^{x} sec (x))

Wende die Produktregel an:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = 2^{x}, g = sec (x)

= \frac{d}{d x} (2^{x}) sec (x) + \frac{d}{d x} (sec (x)) 2^{x}

\frac{d}{d x} (2^{x}) = 2^{x} ln (2)

\frac{d}{d x} (sec (x)) = sec (x) tan (x)

= 2^{x} ln (2) sec (x) + sec (x) tan (x) \cdot 2^{x}

y^{^{''}} + 2 y^{^{'}} + y = 64 e^{(7 t)}

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

\frac{\partial}{\partial x} (\frac{2 x}{2 y})

d er i v a t i v e 3^{x^{2}}

y^{^{'}} = \frac{3 sec ( y )}{( x - 4 ) ^{2}}
