Question 1177187
.
Owen is jumping on a trampoline. When his feet hit the deck of the trampoline, the material depresses 
to a minimum height of 2cm. On average, Owen is reaching a maximum height of 200cm every 10 seconds. 
Determine the equation of a sinusoidal function that would model this situation, assuming Owen reaches his first maximum at 6 seconds.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~



        The answer in the post by  @CPhill is  INCORRECT.



The function    h(t) = 99*sin((π/5)(t-6)) + 101    in the post by  @CPhill 


does not satisfy the condition  " Owen reaches his first maximum at 6 seconds ".



A correct answer,  satisfying all problem's conditions,  is


            h(t) = 99*cos((π/5)(t-6)) + 101.



Although this formula contains the cosine function,  nevertheless, 
it belongs to the class of so called  " sinusoidal functions ".

                Regarding the post by @CPhill . . . 



Keep in mind that @CPhill is a pseudonym for the Google artificial intelligence.


The artificial intelligence is like a baby now. It is in the experimental stage 
of development and can make mistakes and produce nonsense without any embarrassment.



                It has no feeling of shame - it is shameless.



This time, again,  it made an error.



Although the @CPhill' solutions are copy-paste  Google  AI solutions,  there is one essential difference.


Every time,  Google  AI  makes a note at the end of its solutions that  Google  AI  is experimental
and can make errors/mistakes.


All @CPhill' solutions are copy-paste of  Google  AI  solutions, with one difference:
@PChill never makes this notice and never says that his solutions are copy-past that of Google.
So,  he  NEVER  SAYS  TRUTH.


Every time,  @CPhill embarrassed to tell the truth.

But I am not embarrassing to tell the truth,  as it is my duty at this forum.



And the last my comment.


When you obtain such posts from @CPhill,  remember,  that  NOBODY  is responsible for their correctness, 
until the specialists and experts will check and confirm their correctness.


Without it,  their reliability is  ZERO and their creadability is  ZERO,  too.
