(d^2)/(dx^2)(cos(5x))

Lösung

\frac{d ^{2}}{d x ^{2}} (cos (5 x))

- 25 cos (5 x)

Schritte zur Lösung

\frac{d ^{2}}{d x ^{2}} (cos (5 x))

\frac{d}{d x} (cos (5 x)) = - sin (5 x) \cdot 5

= \frac{d}{d x} (- sin (5 x) \cdot 5)

\frac{d}{d x} (- sin (5 x) \cdot 5) = - 25 cos (5 x)

= - 25 cos (5 x)

x \to 0 lim (\frac{a ^{x} - b ^{x}}{x})

n or ma l y = 2 x^{2}, (- 2, 8)

\int_{0}^{5} (t^{2} + 2 t - 15) d t

t \to 0 lim (\frac{5}{t} - \frac{5}{e ^{t} - 1})

a re a y = x^{2} - 1, x = - 2, x = 1
