$\frac{\cos (7 \cdot 2) - \cos (3 \cdot 2)}{\sin (7 \cdot 2) - \sin (3 \cdot 2)} = \frac{- 2 \sin (5 \cdot 2) \cdot \sin (2 \cdot 2)}{2 \sin (5 \cdot 2) \cdot \cos (2 \cdot 2)}$

Step 1

The left side $- 0.17632698$ does not equal to the right side $- 0.06992681$ , which means that the given statement is false.
