derivative cos(7x)

Lösung

ableitung von

cos (7 x)

- sin (7 x) \cdot 7

Schritte zur Lösung

\frac{d}{d x} (cos (7 x))

Wende die Kettenregel an:

- sin (7 x) \frac{d}{d x} (7 x)

= - sin (7 x) \frac{d}{d x} (7 x)

\frac{d}{d x} (7 x) = 7

= - sin (7 x) \cdot 7

x \to - 1 - lim ({2 x^{2} - 5 x})

\frac{d}{d x} (3 sec^{2} (π x - 1))

t an g e n t f (x) = \frac{x ^{2}}{x + 1}, at x = 2

\int 20 (e^{\frac{3}{4} x} - e^{2 x}) d x

\int_{4}^{\infty} 7 e^{- \frac{y}{2}} d y
