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

Step 1

Multiply $2$ by $0.001$ .

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

Step 2

Raise $0.001$ to the power of $2$ .

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

Step 3

Evaluate $\cos (0.002)$ .

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

Step 4

Evaluate $\cos (0.001)$ .

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

Step 5

Multiply $- 1$ by $0.99999999$ .

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

Step 6

Subtract $0.99999999$ from $0.99999999$ .

$\frac{0}{0.000001}$

Step 7

Divide $0$ by $0.000001$ .

$- 0.00045692$
