Hi, sorry again for asking the same question but I had 2 more questions but instead of the diameter, it focuses on max and min.
The 1st question has a max height of 120m and min height of 2m. And completes 1 cycle in 2 min.
My answer to this question is y= sin180t + 118, would that be correct? And what would 1 cycle look like?
The 2nd question has a max height of 25m and min height of 2m. And completes 1 cycle in 5 seconds. My answer to this question is y=cos36t + 23, would that be correct as well? And what would it look like in 1 cycle? Thanks again.

Let's concentrate one at a time

The 1st question has a max height of 120m and min height of 2m. And completes 1 cycle in 2 min. My answer to this question is y= sin180t + 118, would that be correct? And what would 1 cycle look like?



Does that make sense?

I think the answer is this:

In that case just change the sine to cosine, doesn't change anything
