derivative of 1-4cos(x)

Lösung

\frac{d}{d x} (1 - 4 cos (x))

4 sin (x)

Schritte zur Lösung

\frac{d}{d x} (1 - 4 cos (x))

Wende die Summen-/Differenzregel an:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{d}{d x} (1) - \frac{d}{d x} (4 cos (x))

\frac{d}{d x} (1) = 0

\frac{d}{d x} (4 cos (x)) = - 4 sin (x)

= 0 - (- 4 sin (x))

\int_{- 2}^{2} \frac{1}{x ^{2} - 9} d x

\frac{d v}{d t} = 9.8 - v

\int \frac{x ( x - 8 )}{( x - 4 ) ^{3}} d x

x \to 1 lim (\frac{2 x - 7}{4 x + 5})

\int \frac{- x ^{2} + 2 x - 8}{( x ^{2} + 4 ) ( x - 2 )} d x
