d/(dθ)(cos(2θ))

Lösung

\frac{d}{d θ} (cos (2 θ))

- sin (2 θ) \cdot 2

Schritte zur Lösung

\frac{d}{d θ} (cos (2 θ))

Wende die Kettenregel an:

- sin (2 θ) \frac{d}{d θ} (2 θ)

= - sin (2 θ) \frac{d}{d θ} (2 θ)

\frac{d}{d θ} (2 θ) = 2

= - sin (2 θ) \cdot 2

\frac{d}{d x} (\frac{1}{3} \cdot x^{3})

t \to 0 lim (\frac{1}{2} e^{- 2 t})

\frac{d}{d x} (\frac{2}{2 - cos ( π x )})

\frac{\partial}{\partial x} (- x ln (x) + x ln (y) + y)

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