Vector: A vector is a quantity that has magnitude and direction. Tangent is a line that the curve at a single point. Normal is a line that is perpendicular to the curve. Answer and Explanation: r(t)=(3t2,3t+t3...
#Note: This step is risky if the vector is near-tangent with the earth. #Only use when you know the vector is coming in roughly vertical to the surface. length_guess = 1 while(norm(origin + unit_vector_toward_ground * length_guess) > RE): print(norm(origin + unit_vector_toward_gro...
However, interestingly, we can find a certain geodesic with tangent vector vμ such that vνvσ Lνσ is still constant along the geodesics, i.e., vμ∇μ(4)(vν vσ Lνσ ) = 24(κξ − − 1)(mr a2)2 4 vθ vφ2 sinθ cosθ = 0. (D2) The fixed-angle ...

unit_vector_toward_ground = normalize(vec_from_moon_to_sat) #Step 2: Do a binary search to find required vector length. #Step 2a: First, extend the vector over and over until you punch through the earth. #Note: This step is risky if the vector is near-tangent with the earth. #...
