$\frac{\cos (2 (- 0.1)) - \cos (- 0.1)}{{(- 0.1)}^{2}}$

Step 1

Multiply $2$ by $- 0.1$ .

$\frac{\cos (- 0.2) - \cos (- 0.1)}{{(- 0.1)}^{2}}$

Step 2

Raise $- 0.1$ to the power of $2$ .

$\frac{\cos (- 0.2) - \cos (- 0.1)}{0.01}$

Step 3

Evaluate $\cos (- 0.2)$ .

$\frac{0.98006657 - \cos (- 0.1)}{0.01}$

Step 4

Evaluate $\cos (- 0.1)$ .

$\frac{0.98006657 - 1 \cdot 0.99500416}{0.01}$

Step 5

Multiply $- 1$ by $0.99500416$ .

$\frac{0.98006657 - 0.99500416}{0.01}$

Step 6

Subtract $0.99500416$ from $0.98006657$ .

$\frac{- 0.01493758}{0.01}$

Step 7

Divide $- 0.01493758$ by $0.01$ .

$- 1.49375874$
