Hi,
I have my calculator in radians. I just need to know what to put in. I tried doing this but values I was getting didn't seem right.
Any help with this would be greatly appreciated.
Thanks

I checked the values already listed in the table and they were correct. Here is one of them:
$\displaystyle y=5-3\sin\left(\frac{\pi t}{6}+\frac{\pi}{4}\right)$
If t = 4,
$\displaystyle y=5-3\sin\left(\frac{4\pi }{6}+\frac{\pi}{4}\right)=4.22354265\approx 4.22$
Be sure you entered correctly in your calculator. Here is the sequence for the one I just did.
$\displaystyle 5 - 3 sin((4 \pi / 6 + (\pi / 4))$
You replace t with 3. When you do you get:
$\displaystyle 5 - 3 sin(({\color{red}3} \pi / 6 + (\pi / 4))=2.88$
If t=24, then
$\displaystyle 5 - 3 sin(({\color{red}24} \pi / 6 + (\pi / 4))=2.88$
Here's your table
(t, y)= (0, 288), (1, 2.10), (2, 2.10), (3, 2.88), (4, 4.22), (5, 5.78), (6, 7.12), (7, 7.90), (8, 7.90), (9, 7.12), (10, 5.78), (12, 2.88), (14, 2.10), (16, 4.22), (18, 7.12), (24, 2.88)
