Determine the domain of the function
The domain is .
The given function is .
an object attached to a coiled spring is pulled down a distance a from its rest position and then released. Assuming that the motion is simple harmonic with period T, write an equation that relates the displacement d of the object from its rest position after t seconds. Also assume that the positive direction of the motion is up:
Designing an Awning An awning that covers a sliding glass door that is 88 inches tall forms an angle of 50° with the wall.
