$\frac{\cos (2 (0.001)) - \cos (0.001)}{{0.001}^{2}}$

Passaggio 1

Moltiplica $2$ per $0.001$ .

$\frac{\cos (0.002) - \cos (0.001)}{{0.001}^{2}}$

Passaggio 2

Eleva $0.001$ alla potenza di $2$ .

$\frac{\cos (0.002) - \cos (0.001)}{0.000001}$

Passaggio 3

Calcola $\cos (0.002)$ .

$\frac{0.99999999 - \cos (0.001)}{0.000001}$

Passaggio 4

Calcola $\cos (0.001)$ .

$\frac{0.99999999 - 1 \cdot 0.99999999}{0.000001}$

Passaggio 5

Moltiplica $- 1$ per $0.99999999$ .

$\frac{0.99999999 - 0.99999999}{0.000001}$

Passaggio 6

Sottrai $0.99999999$ da $0.99999999$ .

$\frac{0}{0.000001}$

Passaggio 7

Dividi $0$ per $0.000001$ .

$- 0.00045692$
