8

Schritte zur Lösung

x \to 0 lim (\frac{1 - cos ( 8 x )}{4 x ^{2}})

x \to a lim [c \cdot f (x)] = c \cdot x \to a lim f (x)

= \frac{1}{4} \cdot x \to 0 lim (\frac{1 - cos ( 8 x )}{x ^{2}})

\frac{1}{4} \cdot \frac{64 cos ( 8 \cdot 0 )}{2} : 8

= 8

\frac{\partial}{\partial x} (8 x^{9 y})

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

\frac{d}{d x} (\frac{3 x + 6}{2 x + 3})

y^{^{''}} + 80 y^{^{'}} + 1200 y = 0
