**Trigonometric Identities and Formulas** --- ### Problems: **6. Use the triangle to find \(\sin(2β)\), \(\cos(2β)\), \(\sin( \frac{π}{2})\), \(\cos( \frac{π}{2})\)** **Diagram:** - Right triangle with sides 24, 25, and hypotenuse 25. - Angles are denoted as \( α \) and \( β \). **Explanation of Diagram:** - In the given right triangle, the side opposite angle \( β \) is 24 units long. - The side adjacent to angle \( β \) is 7 units long. - The hypotenuse, opposite angle \( α \), is 25 units long. **7. Write the exact answer for \(\cos( \frac{π}{3}) \sin ( \frac{π}{4})\)** **8. Write the exact answer for \(\cos( \frac{5π}{12}) + \cos ( \frac{7π}{12})\)** --- For more detailed solutions and explanations, please refer to your trigonometric identity and formula guides or textbooks.
