SOMEONE PLEASE HELP ME The moon's distance from Earth varies in a periodic way that can be modeled by a trigonometric function.

When the moon is at its perigee (closest point to Earth), it's about 363,000 km away. When it's at its

apogee (farthest point from Earth), it's about 406,000 km away. The moon's apogees occur 27.3 days

apart. The moon will reach its apogee on January 2, 2016.

Find the formula of the trigonometric function that models the distance D between Earth and the moont

days after January 1, 2016. Define the function using radians.

D(t)=
