(d^2)/(dx^2)(cos(7x))

Lösung

\frac{d ^{2}}{d x ^{2}} (cos (7 x))

- 49 cos (7 x)

Schritte zur Lösung

\frac{d ^{2}}{d x ^{2}} (cos (7 x))

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

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

\frac{d}{d x} (- sin (7 x) \cdot 7) = - 49 cos (7 x)

= - 49 cos (7 x)

y^{^{'}} = 3 x (y + 4)^{2}

f (t) = t - 4

\int \frac{6 x ^{2} - 5 x + 8}{x ^{3} + 4 x} d x

\int_{0}^{4} 16 x^{2} - x^{4} d x

\frac{\partial}{\partial x} (x^{2} sin (6 t))
