To find the distance to the moon, humans first had to find the size of the earth.  So they knew the radius of the earth (about 4000 miles) and they also were able to measure angle E.  Hence, using the figure above, what is the equation used to find the distance from the center of the earth to the moon?

Find all the second order partial derivatives of the given function.f(x, y) = x2 + y – ex+y

Find all the second order partial derivatives of the given function.f(x, y) = x2 + y – ex+y

Match the identities for negative angles.*   *For the tangent, you should be able to figure it out using the fact that tangent is the sine divided by the cosine.
