Question

Write a sine and cosine function that models the data in the table. I need steps to both the sine function and cosine function for a, b, c, and d. (I can't attach the pictures here.)

Please help me, I don't know what to do, and my teacher's video isn't much help either.

There are lots of other videos online, I guarantee ...
