Step 1.1

Multiply $2$ by $0.5$ .

$a = - 2.8 \sin (1) - 0.1 \cos (0.5)$

Step 1.2

Evaluate $\sin (1)$ .

$a = - 2.8 \cdot 0.84147098 - 0.1 \cos (0.5)$

Step 1.3

Multiply $- 2.8$ by $0.84147098$ .

$a = - 2.35611875 - 0.1 \cos (0.5)$

Step 1.4

Multiply $- 0.1$ by $\cos (0.5)$ .

$a = - 2.35611875 - 0.08775825$

$a = - 2.35611875 - 0.08775825$

Step 2

Subtract $0.08775825$ from $- 2.35611875$ .

$a = - 2.44387701$
