1. The problem statement, all variables and given/known data Find the vector directed from (10,3π/4,π/6) to (5, π/4,π), where the endpoints are given in spherical coordinates. Ans -9.660ax, - 3ay. + 10.61az 2. Relevant equations az=rCosΦ 3. The attempt at a solution az=10Cos(π/6) +5Cos(π) =13.6 My answer differs. Where did i go wrong?
