Please go on to MATLAB and answer the following in code please.
Use "Wolfram Documentation" under...
Use "Wolfram Documentation" under the help menu to learn more about working with vectors in Mathematica. OperationsOnVectors and VectorsAndMatrices both have a lot of helpful information. 1. Determine a unit vector in the direction of the displacement from the point(3,0,1) to the point(3,2,-1). 2. Use vectors to calculate, correct to the nearest degree, the three angles of a triangle with vertices (3,0,1), (3,2,-1) and (1,3,2).
