Write down the following transformed sin or cos functions. Round all numbers to 3 SDs whenever necessary.
1. sin function, amp = 4.7, frequency = 50Hz, phase = 34°
2. cos function, amp = 0.3, frequency = 0.08 Hz, phase = 2 s
3. cos function, amp = 0.0071, frequency = 1000 Hz, phase = $-\frac{\pi}{3}$
4. sin function, amp = 1, period = 2 s, phase = 0.3 s
5. sin function, amp = 50, period = 0.05 s, phase = 150° to the right
6. cos function, amp = 0.28, period = 5 ms, phase = $\frac{3\pi}{8}$ to the left
7. sin function, amp = 2000, period = 60°, phase = 5°
8. cos function, amp = 6.3 x $10^5$, period =15$\pi$, phase = -$\pi$
9. sin function, amp = 0.04, period = $\frac{\pi}{8}$, phase = 1° to the right
