Step 2.1.1.1

Multiply $0$ by $8$ .

$d = 3 \sin (0 π) - 2$

Step 2.1.1.2

Multiply $0$ by $π$ .

$d = 3 \sin (0) - 2$

$d = 3 \sin (0) - 2$

Step 2.1.2

The exact value of $\sin (0)$ is $0$ .

$d = 3 \cdot 0 - 2$

Step 2.1.3

Multiply $3$ by $0$ .

$d = 0 - 2$

$d = 0 - 2$

Step 2.2

Subtract $2$ from $0$ .

$d = - 2$

$d = - 2$
