Find the Exact Value sin(3)cos(1.2)-cos(3)sin(1.2)

$\sin (3) \cos (1.2) - \cos (3) \sin (1.2)$

Step 1

Simplify each term.

Evaluate $\sin (3)$ .

$0.05233595 \cos (1.2) - \cos (3) \sin (1.2)$

Multiply $0.05233595$ by $\cos (1.2)$ .

$0.05232447 - \cos (3) \sin (1.2)$

Evaluate $\cos (3)$ .

$0.05232447 - 1 \cdot 0.99862953 \sin (1.2)$

Multiply $- 1$ by $0.99862953$ .

$0.05232447 - 0.99862953 \sin (1.2)$

Multiply $- 0.99862953$ by $\sin (1.2)$ .

$0.05232447 - 0.02091371$

$0.05232447 - 0.02091371$

Step 2
