Thread: sinusoidal function

The curve above is the graph of a sinusoidal function. It goes through the point and . Find a sinusoidal function that matches the given graph. If needed, you can enter =3.1416... as 'pi' in your answer, otherwise use at least 3 decimal digits.

Anyone can help me on how to solve this???

Thank you

P.

If you are looking for the sinusoidal functions for the graph then i believe this is the answer(s):

y=2cos[(x-3/2)]+1

y=2sin[(x-1)]+1

How:

Using the equation for a sinusoidal function: y=af[b(x-h)]+k

Hi,

I need the answer in the form

Asin(b(x-c)

Thanks
